Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail with reference to the accompanying drawings.

Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

With the increase of terminal base, the load of the search server is getting heavier, causing a large number of terminals to access the search server during the same period of time, resulting in slower processing speed of the search server or even downtime, causing the terminal to fail to obtain search results in time , Resulting in lower search efficiency.

In related technologies, the search gateway often reduces the load on the search server by downgrading the search request. Among them, the commonly used downgrade processing method is to abandon the search request when the search gateway determines that the downgrade processing is needed, that is, when the downgrade processing is required, the search request is no longer sent to the search server. Alternatively, the search gateway caches part of the core data of the search server locally, and when downgrading processing is required, the search gateway obtains the search result from the local cache and returns it to the client.

Fig. 1 is a system architecture diagram involved in an information search method according to an exemplary embodiment. The system architecture diagram includes a terminal 101, a search gateway 102, and a search server 103.

The terminal 101 and the search gateway 102 conduct data interaction through a network connection, and the search gateway 102 and the search server 103 conduct data interaction through a network connection. The terminal 101 may run an application program for searching, and the application program may be an application program with an information search function such as a browser or an Internet transaction platform. Users can search for information through this application. Correspondingly, when the terminal 101 receives a search instruction triggered by the user, it generates a first search request according to the search instruction, and sends the first search request to the search gateway 102. In response to the normal operation of the search server 103, the search gateway 102 forwards the first search request to the search server 103, and the search server 103 searches for the service data corresponding to the first search request according to a preset search algorithm, and returns the searched service data to The search gateway 102 returns the service data to the terminal 101 by the search gateway 102. In response to the abnormal operation of the search server 103, the search gateway 102 obtains the service data corresponding to the first search request from the cache according to the first search request, and then returns the service data to the terminal 101.

For example, the application program may be an Internet trading platform, and the display interface of the application program displays a search bar, and the user can input the first search request information corresponding to the search target into the search bar. For example, the user's search target may be a restaurant in a certain place , The first search request information input by the user may be "a restaurant in area A". Correspondingly, the terminal 101 generates a first search request according to the first search request information, and sends the first search request to the search gateway 102. The search gateway 102 obtains the service data corresponding to the first search request. Correspondingly, the service data corresponding to the first search request may be data such as the name, location, and relevant user comments of the restaurant in place A.

In a possible implementation manner, the system architecture further includes a cache server in which service data is cached. In response to the abnormal operation of the search server 103, the search gateway 102 may directly obtain the service data cached in the cache server from the cache server, and send the service data to the terminal 101.

Wherein, the terminal 101 may be a mobile phone, a computer, a tablet computer, a wearable device, or the like. Both the search server 103 and the cache server may be independent physical servers, may also be a server cluster composed of multiple physical servers, or may also be cloud servers. The search gateway 102 can be any network connector or protocol converter that can perform protocol conversion, which is not specifically limited in the embodiments of the present disclosure.

Fig. 2 is a flow chart showing an information search method according to an exemplary embodiment. As shown in Fig. 2, the information search method includes the following steps:

Step 201: Receive a first search request sent by a terminal, and obtain first search request information corresponding to the first search request.

Step 202: In response to the need to downgrade the first search request and the first service data corresponding to the first search request information does not exist in the cache, modify the first search request information to obtain second search request information, The second service data corresponding to the second search request information exists in the cache.

Step 203: Obtain the second service data corresponding to the second search request information from the cache according to the second search request information.

Step 204: Return the second service data to the terminal.

In the embodiment of the present disclosure, in the embodiment of the present disclosure, the first search request sent by the terminal is received, and the first search request information corresponding to the first search request is obtained; in response to the need to downgrade the first search request and the cache is There is no first service data corresponding to the first search request information, the first search request information is modified to obtain the second search request information, and the second service data corresponding to the second search request information exists in the cache; according to the second search request Information, the second service data corresponding to the second search request information is obtained from the cache; the second service data is returned to the terminal, so that when the first search request is downgraded, the search gateway can ensure that the search gateway obtains the cached service data The service data is returned to the terminal, thereby ensuring that the search request sent by the terminal can be responded to, and improving the response rate of the search request.

In the embodiment of the present disclosure, the terminal sends the first search request to the search gateway, and the search gateway determines whether the first search request needs to be downgraded. Referring to FIG. 3, in response to the search gateway determining that the first search request needs to be downgraded, the search gateway determines the downgrade strategy corresponding to the first search request according to the first search request information included in the first search request. In response to the first search request including the first location information for indicating the longitude and latitude information, the search gateway performs a downgrade strategy with the longitude and latitude on the first search request according to the first location information. In response to the first search request not including the first location information indicating the latitude and longitude information, the search gateway performs a downgrade strategy for the first search request without latitude and longitude according to the search indication information contained in the first search request information.

Fig. 4 is a flowchart of an information search method according to an exemplary embodiment. This embodiment takes the search gateway to execute a downgrade strategy with latitude and longitude as an example for description. As shown in Fig. 4, the information search method includes the following steps:

Step 401: The search gateway receives the first search request sent by the terminal, and obtains the first search request information corresponding to the first search request.

The first search request information includes at least first location information and search indication information. Wherein, the first location information is location information provided by the terminal; the search instruction information is instruction information used to indicate a search target. The first search request information may also include other auxiliary search information used to assist the search.

In a possible implementation manner, the first search request information includes first location information and search indication information; and, the first search request carries first location information and search indication information. Correspondingly, the process for the search gateway to obtain the first location information and the search indication information may be: the search gateway obtains the first location information and the search indication information from the first search request.

The first search request carries encrypted first location information and encrypted search indication information. Correspondingly, the process for the search gateway to obtain the first location information and the search indication information may be: the search gateway decrypts the first search request to obtain the first location information and the search indication information.

Correspondingly, when the first search request carries the encrypted first location information and the encrypted search indication information, before the terminal sends the first search request to the search gateway, the terminal encrypts the first location information and the search indication information, and encrypts the encrypted first location information and search indication information. The first location information and the encrypted search instruction information are added to the first search request. Among them, the encryption method of the terminal corresponds to the decryption method of the search gateway. The terminal and the search gateway agree on an encryption and decryption method in advance, the terminal encrypts the first search request information according to the preset encryption method, and the search gateway decrypts the first search request according to the decryption method agreed in advance. Among them, the preset encryption method is a previously agreed encryption method.

In this implementation manner, decryption processing is performed through the first search request to obtain the first location information and search indication information corresponding to the first search request, thereby increasing the security of the first search request.

In another possible implementation manner, the first search request information also includes auxiliary search information; correspondingly, the process for the search gateway to obtain the auxiliary search information may be: the search gateway calls the external server according to the first search request; The auxiliary information corresponding to the first search request is obtained from the external server. For example, the auxiliary search information may include source information of the first search request. Correspondingly, the auxiliary search information may be the cityid of the first search request, and the cityid corresponding to the first search request is obtained by calling the cityid gateway server.

When the first search request information also includes auxiliary search information, the process for the terminal to obtain the first search request information may be: decrypting the first search request to obtain the first location information corresponding to the first search request And search indication information, and, according to the first search request, the auxiliary search information corresponding to the first search request is obtained; the first location information, the search indication information, and the auxiliary search information form the first search request corresponding to the first search request. A search request information.

Wherein, the first location information may be the location information of the geographic location where the terminal is located when the first search request is sent. Correspondingly, the terminal locates the current geographic location, determines the current location coordinates, and adds the location coordinates to The first search request. For example, the terminal may perform positioning through the positioning system provided by the terminal, and determine the position coordinates obtained by positioning as the first position information. The first location information may also be location information selected or input by the user received by the terminal. Correspondingly, the terminal receives the location information input by the user, converts the location information input by the user into location coordinates, and adds the location coordinates to the first search. Requesting. For example, if the position information input by the user is "A street B intersection", the terminal converts the position information into position coordinates corresponding to "A street B intersection", and uses the position coordinates as the first position information.

It should be noted that the search gateway may first decrypt the first search request and then obtain the auxiliary search information corresponding to the first search request; the search gateway may also first obtain the auxiliary search information corresponding to the first search request before making the first search request Perform decryption processing; the search gateway can also obtain the auxiliary search request corresponding to the first search request and decrypt the first search request at the same time. In the embodiment of the present disclosure, there is no aggregate restriction on the processing flow of the gateway server for the first search request.

Step 402: The search gateway determines whether to perform downgrade processing on the first search request.

Referring to FIG. 5, after receiving the first search request, the search gateway determines whether the first search request needs to be downgraded. Wherein, the search gateway may determine whether to downgrade the first search request according to the state of the search server. The search gateway can determine whether to downgrade the first search request in the following three ways. In the first implementation mode, the search gateway can select eligible search requests for downgrade processing when downgrading the search request. In the second implementation manner, the search gateway can determine whether to downgrade the first search request according to the non-result rate of the search server; in the third implementation manner, the search gateway can also, when it does not receive the service data returned by the search server, It is determined that the first search request needs to be downgraded.

Correspondingly, in the first implementation mode, the search gateway can select search requests that meet the conditions for downgrade processing when downgrading the search request. Wherein, the condition may be that the hash value of the first search request satisfies the requirement of an increase in the non-result rate. Correspondingly, the search gateway can obtain the hash value corresponding to the first search request by performing a hash calculation on the unique identifier of the first search request, and perform the remainder calculation on the hash value corresponding to the first search request, and take The value after the remainder is differentiated, so that the first search request whose percentage value after the remainder is less than the increase in the rate of no results is selected for downgrading. Wherein, the method for the search gateway to determine the search request that meets the conditions according to the unique identifier of the first search request can be expressed by Formula 1.

Formula 1: hash(queryid)%100/100

Among them, queryid represents the unique identifier of the first search request; hash(queryid) represents the hash value of the unique identifier of the first search request obtained by hashing the unique identifier of the first search request; hash(queryid)% 100 represents the remainder calculation of the hash value of the unique identifier of the first search request; hash(queryid)% 100/100 represents the percentage value of the hash value of the unique identifier of the first search request after the remainder.

In this implementation manner, the first search request that can be downgraded is selected through the hash value of the first search request, thereby preventing all first search requests from being downgraded, and the search server cannot receive the first search request during normal operation. One search request ensures that the number of degraded first search requests is reasonable, so that the first search request is automatically degraded.

In the second implementation manner, the search gateway determines whether to downgrade the first search request according to the predetermined working status of the search server. The search gateway determines whether the first search request needs to be downgraded according to the non-result rate. This process can be achieved through the following steps (A1)-(A4), including:

(A1) The search gateway obtains the current non-result rate of the search server.

The search gateway counts the number of search requests sent to the search server within the first specified time period, and counts the number of search requests that receive empty data in these search requests, and compares the number of search requests that receive empty data with the number of search requests sent The ratio of the total number is determined as the current non-result rate of the search server. The empty data may be a response returned by the search server that does not include the service data corresponding to the first search request, or it may be that the search gateway has not received the service data returned by the search server. The first designated duration can be set as required, and in the embodiment of the present disclosure, the first designated duration is not specifically limited. For example, the first designated duration may be 10s, 15s, 20s, etc.

Among them, the reason why the search gateway receives empty data may be that the number of search requests processed by the search server exceeds the preset threshold, so that the search server responds to the search request sent by the search gateway for longer than the second specified time period; or the search server is down , Program bugs (vulnerabilities) and other exceptions. In the embodiments of the present disclosure, the types of problems generated by the search server are not specifically limited. Wherein, the second designated duration is less than the first designated duration, and the second designated duration can be set as required, which is not specifically limited in the embodiments of the present disclosure.

(A2) The search gateway obtains the benchmark non-result rate of the search server.

Among them, the reference non-result rate can be determined according to the non-result rate of the search server in different designated time periods. For example, the specified time period may be within a time period of 10 minutes, 1 hour, 1 day, or 1 week, etc., and the reference non-result rate of the search server is determined through the non-result rate determination model. The non-result rate determination model may be a linear model. In the embodiment of the present disclosure, the non-result rate determination model is not specifically limited.

In a possible implementation manner, the reference non-result rate may be determined by the search gateway itself. Accordingly, the search gateway determines the reference non-result rate every third specified time period, and the search gateway determines the reference non-result rate. It can be: the search gateway determines the benchmark non-result rate of the search server through the above-mentioned non-result rate determination model; stores the benchmark non-result rate locally, and the search gateway obtains the benchmark non-result rate from the local storage every third specified period of time .

In another possible implementation manner, the reference non-result rate may be determined by other electronic devices, the process of determining the reference non-result rate of the search server by other electronic devices, and the process of determining the reference non-result rate of the search server by the search gateway It is similar, so I won't repeat it here. Correspondingly, when the search gateway needs to obtain the reference non-result rate of the search server, it may send a non-result rate obtaining request to other electronic devices, and the non-result rate obtaining request carries at least the gateway identification of the search gateway and the server identification of the search server; When other electronic devices receive the request for obtaining no result rate, they obtain the reference no result rate of the search server according to the server ID of the search server, and send the reference no result rate to the search gateway according to the gateway ID of the search gateway, and search The gateway receives the reference non-result rate of the search server sent by other electronic devices.

Another point that needs to be explained is that the search gateway can first obtain the current non-result rate of the search server, and then obtain the reference non-result rate of the search server; the search gateway can also first obtain the reference non-result rate of the search server and then obtain the current non-result rate of the search server. Result rate: The search gateway can also obtain the current non-result rate and the reference non-result rate of the search server at the same time, which is not specifically limited in the embodiment of the present disclosure. That is, the search gateway can perform step (A1) and then step (A2), the search gateway can also perform step (A2) and then step (A1), and the search gateway can also perform steps (A1) and (A2) at the same time. . In the embodiment of the present disclosure, the order in which steps (A1) and (A2) are executed by the search gateway is not specifically limited.

(A3) The search gateway determines the current non-result rate increment based on the current non-result rate and the benchmark non-result rate.

The search gateway uses the difference between the current non-result rate and the reference non-result rate as the increase in the non-result rate of the search server. That is, the increase in the non-result rate P1 = the current non-result rate-the reference non-result rate.

(A4) In response to the increase in the non-result rate being greater than the preset threshold, the search gateway determines that the first search request needs to be downgraded.

The search gateway may directly determine that the first search request is a search request that needs to be degraded when the increase in the non-result rate is greater than the preset threshold. The search gateway may also determine whether to degrade the current search request in combination with the current degradation rate, and determine whether the first search request is a search request that needs to be degraded based on the current degradation rate. Correspondingly, the search gateway determines the current degraded search rate; in response to the current degraded search rate being less than the ineffective rate increment, the search gateway executes step (A4). Wherein, the current degraded search rate may be determined according to the number of degraded search requests in the current time period and the total number of search requests in the current time period.

In this implementation manner, by combining the current unresult rate increment and the current degradation rate, it is determined whether to downgrade the first search request, so that when the search server exceeds the load, only part of the search request is downgraded, thereby When the load of the search server is reduced, the search gateway can automatically stop downgrading the search request to automatically resume the search.

In this implementation, the search gateway determines whether to downgrade the first search request according to the current working status of the search server, so that the search gateway can determine the current working status of the search server and determine whether to make the first search request Perform downgrade processing, so as to automatically downgrade the first search request according to the working status of the search server, so as to prevent the search server from working abnormally, you can downgrade the first search request to obtain the service data corresponding to the search request, and prevent The terminal cannot obtain the service data, which affects the user experience.

The third implementation manner, continue to refer to Figure 5, the search gateway can send the first search request to the search server. If the service data returned by the search server is not received within the first preset time period, it is determined that the first search request is required Perform downgrade processing. The process may be: in response to not receiving the search result returned by the search server within the first preset time period, the search gateway determines that the first search request needs to be downgraded.

It should be noted that when the search gateway receives the first search request, it can first directly send the first search request to the search server. When the service data returned by the search server is not received within the first preset time period, it is determined The first search request needs to be degraded; the search gateway may also perform steps (A1)-(A3) first when receiving the first search request, and in response to the increase in the rate of no results being not greater than the preset threshold, the search The server sends the first search request, and when the service data returned by the search server is not received within the first preset time period, it is determined that the first search request needs to be downgraded.

In this implementation, the search gateway determines whether the search request needs to be downgraded according to whether the service data returned by the search server is received within the first preset time period, so that the search gateway can, when the search server cannot return the service data in time, The first search request is degraded to ensure that the terminal can obtain the service data corresponding to the first search request, thereby ensuring user experience.

In addition, the search gateway may also determine whether to perform downgrade processing on the first search request according to the accuracy requirements of the first search request for the service data. Correspondingly, when the search server determines that the first search request needs to be downgraded, the search gateway may determine the accuracy requirements of the first search request for the service data. In response to the accuracy requirement corresponding to the first search request being lower than the target accuracy requirement, the first search request is degraded. In response to the accuracy requirement corresponding to the first search request being not lower than the target accuracy requirement, no downgrade processing is performed on the first search request. For example, the first search request may carry indication information used to indicate the accuracy requirement type of the first search request. The search server determines the accuracy requirement corresponding to the first search request information according to the indication information. For example, if the indication information of the first search request indicates that the accuracy requirement type of the first search request is a regular type, it is determined that the first search request can be processed. Downgrade processing. The indication information of the first search request indicates that the accuracy requirement type of the first search request is a high-precision type, and it is determined that the first search request cannot be downgraded.

It should be noted that the search gateway may determine the accuracy requirement type of the first search request before determining whether to downgrade the first search request, and the search gateway may also determine that the first search request needs to be downgraded. The accuracy requirement type of the first search request is determined, which is not specifically limited in the embodiment of the present disclosure.

In this implementation, the accuracy requirement of the first search request on the service data is used to determine whether to downgrade the first search request, thereby ensuring that the first search request with high accuracy requirements may not be downgraded, thereby ensuring that the first search request High-precision service data can be obtained.

Step 403: In response to the need to perform downgrade processing on the first search request, the search gateway queries the cache for the first service data corresponding to the first search request according to the first search request.

Continuing to refer to FIG. 5, when the first search request needs to be downgraded, the search gateway queries the cache for the first service data corresponding to the first search request according to the first search request. The search gateway may match the cached service data according to the search value corresponding to the first search request, so as to query the first service data corresponding to the first search request. Correspondingly, the cache can store multiple service data and the corresponding relationship between the service data and the search value. When the search gateway obtains the service data from the cache, it can query the corresponding relationship between the service data and the search value according to the search value. The first service data corresponding to the first search request. Continuing to refer to Figure 5, in response to the search gateway querying the service data corresponding to the search value of the first search request from the cache, the service data is returned to the terminal as the first service data; Upon searching for service data corresponding to the request, the search gateway executes step 404.

The search value may be determined according to the first search request information carried in the first search request, and the first search request information may include information such as keywords corresponding to the first search request, city information, search type, and sorting method selected by the user. . Correspondingly, the search server converts the first search request information into a search value according to the search value algorithm. In a possible implementation, the search server can directly convert the first search request information into a numerical value to obtain the search value corresponding to the first search request; in another possible implementation, the search server can first determine the first The weights of different information in the search request information are added to the information in the first search request information according to the weights to obtain the search value corresponding to the first search request.

In addition, the cached service data may be core data obtained by the search gateway from the search server in advance, and the cached service data may also be the service data returned by the search server received when the search gateway performs the search service. There is no specific limitation on this. Correspondingly, when the search server returns the service data, it also returns the search value corresponding to the service data, and the search gateway stores the service data and the search value correspondingly.

Wherein, the cache may be a local cache of the search gateway, and the cache may also be a cache in a cache server called by the search gateway. Correspondingly, in a possible implementation manner, the search gateway directly invokes the local cache, and queries the first service data corresponding to the first search request from the current cache according to the search value corresponding to the first search request. In this implementation, the search gateway caches the service data locally, not only can downgrade the first search request when the search server fails, and query the first service data corresponding to the first search request from the local cache, but also This prevents the search gateway from querying the first service data corresponding to the first search request from the local cache when the connection between the search gateway and the external network fails, thereby ensuring that the search gateway can also query the first search request when the network is abnormal The corresponding first service data.

In another possible implementation manner, the search gateway calls a cache server to query the first service data corresponding to the first search request from the cache server. Correspondingly, the process of the search gateway querying the cache for the first service data corresponding to the first search request according to the first search request can be implemented through the following steps (1)-(6), including:

(1) Send the first search request information to a cache server, the cache server is used for caching service data, and according to the first search request information, the first service data corresponding to the first search request information is actually queried.

The search gateway can implement the server interface of the storage cache server, exchange data with the cache server through the server interface of the cache server, and send the first search request to the cache server.

(2) The cache server receives the first search request.

Correspondingly, in this step, the cache server receives the first search request through the server interface.

(3) The cache server queries the cached service data for the first service data corresponding to the first search request according to the first search request.

In this step, the cache server queries the cached service data for the first service data corresponding to the first search request according to the search value corresponding to the first search request.

It should be noted that the search value of the first search request can be determined by the search gateway. Correspondingly, the search gateway can directly send the search value corresponding to the first search request to the cache server. Correspondingly, in this step, the cache The server directly queries the locally cached service data for the first service data of the first search request according to the search value corresponding to the first search request. The search value of the first search request may also be determined by the cache server. Correspondingly, in this step, the cache server determines the search value corresponding to the first search request according to the first search request, and according to the search value corresponding to the first search request Query the first service data corresponding to the first search request from the cached service data.

The process for the cache server to determine the search value corresponding to the first search request is similar to the process for the search gateway to determine the search value corresponding to the first search request, and will not be repeated here.

(4) In response to the absence of the first service data corresponding to the first search request in the cache server, the search gateway executes step 404.

In response to the cache server not querying the first service data corresponding to the first search request from the locally cached service data, the cache server may not send a response corresponding to the first search request to the search gateway, and the search gateway sets the second preset If the response from the cache server is received within the time period, the search gateway determines that the first service data corresponding to the first search request does not exist in the cache server, and the search gateway executes step 404. Or, in response to the cache server not querying the first service data corresponding to the first search request from the locally cached service data, the cache server sends a target response to the search gateway, and the target response is used to indicate that the first service data does not exist in the cache server. If the first service data corresponding to the search request is searched, the search gateway determines that the first service data corresponding to the first search request does not exist in the cache server, and the search gateway executes step 404.

(5) In response to the presence of the first service data corresponding to the first search request in the cache server, the cache server sends the first service data to the search gateway.

In response to the cache server querying the first service data corresponding to the first search request from the locally cached service data, obtain the cached first service data, and send the first service data to the search gateway.

(6) The search gateway receives the first service data returned by the cache server.

In this step, the search gateway receives the first service data returned by the cache server, and sends the first service data to the terminal corresponding to the first search request.

In this implementation, the cached service data is cached in a cache server outside the search gateway, thereby ensuring sufficient cache space, ensuring that a large amount of service data available for search can be cached in the cache, thereby ensuring that the search service can proceed smoothly .

The process of the cache server caching service data is similar to the process of searching the gateway cache service data, and will not be repeated here.

It should be noted that when the search gateway receives the first search request, it can directly query the first service data corresponding to the first search request from the cache according to the first location information included in the first search request. The search network manager can also intercept the first location information in the first search request according to a preset accuracy when receiving the first search request, and query the cache for the first location information corresponding to the first search request according to the intercepted first location information. The first service data. In the embodiments of the present disclosure, this is not specifically limited.

Step 404: In response to the need to perform downgrade processing on the first search request and the first service data corresponding to the first search request information does not exist in the cache, the search gateway modifies the first location information to obtain second location information.

In response to the first location information being carried in the first search request, the search gateway performs downgrade processing on the first search request through a dimensional downgrade strategy. Wherein, the first location information is the first location information carried in the first search request.

Among them, the search gateway can modify the first location information in the following three ways to obtain the second location information. The first implementation is to intercept the first location information according to the preset accuracy; the second implementation is to adjust the location information of the first target field; the third implementation is to delete the location of the second target field information.

Correspondingly, in the first implementation manner, the search gateway intercepts the first location information according to the preset accuracy to obtain the second location information.

In this implementation manner, the search gateway intercepts the number of digits corresponding to the preset accuracy in the first location information according to the preset accuracy to obtain the second location information. Wherein, the preset precision may be a preset precision value, or may be a precision value determined according to a preset precision determination method. For example, the user can pre-set the precision value corresponding to the preset precision to 5 decimal places, and then when the search gateway intercepts any first position information, it will intercept the 5 decimal places of the first position information. Correspondingly, the preset accuracy is an accuracy value determined according to a preset accuracy determination method, and the preset accuracy determination method may be to determine an accuracy value corresponding to the preset accuracy according to the original decimal places of the first position information. For example, the search gateway can choose to intercept 80% of the decimal places of the first location information, and when the first location information has 10 decimal places, the search gateway can intercept the eighth decimal place of the first location information.

In the second implementation manner, the search gateway adjusts the location information of the first target field in the first location information to obtain the second location information.

Wherein, the first target field is a field in the first location information, and the first target field is a preset field. For example, the first target field may be a field such as the last bit or the penultimate bit of the first position information.

When the first position information is a position coordinate, the first target field may be a field in the coordinate information corresponding to any coordinate axis in the position coordinate, or may be a field in the coordinate information corresponding to each coordinate axis in the position coordinate. For example, the first target field is the last position in the position coordinates, and the first position information is 120.45172:28.19126, and the adjusted second position information may be 120.45172:28.19127, 120.45173:28.19126, 120.45173:28.19167, etc. Wherein, the search gateway may randomly determine the coordinate axis information corresponding to the first target field. The search gateway may also determine in advance the coordinate axis information corresponding to the first target field. The search gateway may also determine the coordinate axis information corresponding to the first target field according to the values of different coordinate axes in the first location information. For example, the search gateway may determine the coordinate axis information corresponding to the first target field according to the coordinate value corresponding to each coordinate axis in the first location information. The search gateway may determine the magnitude of the values corresponding to different coordinate axes in the first location information, and determine the adjustment method for the first location information according to the magnitude of the values corresponding to the different coordinate axes. For example, the search gateway may increase the coordinate value corresponding to a coordinate axis with a smaller value in the first location information, or decrease the coordinate value corresponding to a coordinate axis with a larger data in the first location information, and so on. In the embodiments of the present disclosure, this is not specifically limited.

In a third implementation manner, the search gateway deletes the location information of the second target field in the first location information to obtain the second location information.

Wherein, the second target field is a field in the preset first location information. For example, the second target field may be a field such as the last bit or the penultimate bit of the first location information. Moreover, when the first position information is position coordinates, the first target field may be a field in the coordinate information corresponding to any coordinate axis in the position coordinates, or may be a field in the coordinate information corresponding to each coordinate axis in the position coordinates. Field. For example, the first target field is the last position in the position coordinates, and the first position information is 120.45172:28.19126, and the adjusted second position information may be 120.45172:28.1912, 120.4517:28.19126, 120.4517:28.1916, etc.

In addition, the first target field and the second target field may be the same field or different fields, which is not specifically limited in the embodiment of the present disclosure.

One point that needs to be explained is that when the search gateway modifies the first location information, the first location information can be modified through any one of the above three implementation manners. The search gateway may also modify the first location information in combination with at least two of the foregoing three implementation manners, which is not specifically limited in the embodiment of the present disclosure. For example, when the search gateway modifies the first location information in the first search request, it can intercept the first location information through the first implementation method to obtain the third location information, and then modify the third location information. Adjust the first target field of, and/or delete the second target field in the third position information to obtain the second position information. That is, the search gateway intercepts the first location information according to the preset accuracy to obtain the third location information; adjusts the location information of the first target field in the third location information to obtain the second location information . Alternatively, the search gateway intercepts the first location information according to a preset accuracy to obtain the third location information; deletes the location information of the second target field in the third location information to obtain the second location information. Alternatively, the search gateway intercepts the first location information according to the preset accuracy to obtain the third location information; adjusts the location information of the first target field in the third location information, and deletes the third location information. The location information of the second target field in the location information obtains the second location information.

It should be noted that when the first location information is location information that has not been intercepted, the search gateway can select at least one of the above three implementation methods to perform a new strategy of degrading the first search request with latitude and longitude. . When the first location information is the location information that has been intercepted, the search gateway can select at least one implementation from the second implementation and the third implementation to perform a new strategy of downgrading the first search request with latitude and longitude .

In this implementation, the second location information is obtained by modifying the location information in the first search request, so that the accuracy of the location information corresponding to the first search request is reduced, so that the search gateway can obtain the location information from the location information with lower accuracy. Querying the first service data corresponding to the first search request ensures that the search gateway can obtain the service data.

Step 405: The search gateway generates the second search request information according to the second location information and the search indication information used to indicate the search target in the first search request information.

In this step, the search gateway reconstructs the search request information according to the modified second location information to obtain the second search request information. The search gateway may directly combine the second location information and the search indication information in the first search request information to obtain the second search request information; the search gateway may also segment the search indication information in the first search request information, Reorganize according to the word segmentation result to obtain the second search request information.

Correspondingly, in a possible implementation manner, the search gateway composes the second search request information with the second location information and the search indication information in the first search request information.

In this implementation manner, the search gateway replaces the first location information in the first search request with the modified second location information to obtain the second search request information. For example, the first search request is to search for nearby Sichuan restaurants, where the location information carried in the first search request is first location information, and the first search request information corresponding to the first search request is "Sichuan cuisine near the first location information Restaurant”, when the first location information is modified, the second search request information corresponding to the first search request is “Sichuan restaurant near the second location information”.

In this embodiment, by recombining the second location information and the search indication information in the first search request information to obtain the second search request information, the search gateway can search through the modified second search request information, thereby Ensure that the search gateway can obtain service data.

In another possible implementation manner, the search gateway performs word segmentation processing on the search indication information included in the first search request information to obtain a plurality of word segments, and according to the plurality of word segmentation, determines the first part used to represent the fourth location information. A target word segmentation, the fourth position information represented by the first target word segmentation, the second position information, and other word segmentation in the plurality of word segmentation except the first target word segmentation form the second search request information.

In this implementation manner, the search gateway performs word segmentation processing on the search indication information to obtain a plurality of word segments, obtains a first target word segment containing location information from the plurality of word segments, and converts the first target word segment into fourth location information, Thus, the second search request information is composed of the fourth location information, the second location information and other word segmentation. For example, if the search instruction information is "clothing store near A street", the word segmentation of the search instruction information will get two word segmentation ratios of "A street" and "clothing store", where "A street" can indicate For word segmentation of location information, the fourth location information corresponding to "A street" is obtained, and then the fourth location information, the second location information, and the "clothing store" are combined into the second search request information.

Step 406: The search gateway obtains the second service data corresponding to the second search request information from the cache according to the second search request information.

The process in which the search gateway queries the second search request from the cached service data according to the second search request information is the same as the process in which the search gateway queries the first service data corresponding to the first search request from the cache according to the first search request in step 403 The process is similar, so I won't repeat it here.

Continuing to refer to Figure 5, the search gateway queries the cached service data for the second search request information according to the second search request information. When the search gateway queries the second service data corresponding to the second search request information, the cache exists in the cache. For the second service data corresponding to the second search request information, the search gateway obtains the second service data, and step 406 is executed. In response to the search gateway not finding the second service data corresponding to the second search request information, step 404 is executed to modify the second location information in the second search request information to obtain third location information; The information generates the third search request information until the third service data corresponding to the third search request information is obtained from the cache according to the third search request information.

It should be noted that when continuing to modify the second location information in the second search request information, at least one of the three modifications in step 404 can be selected for modification, and when only one modification is selected When the method is modified, in different modification processes, different modification methods may be used alternately, or the same modification method may be used, which is not specifically limited in the embodiments of the present disclosure.

Another point that needs to be explained is that when the search gateway performs word segmentation processing on the search indication information included in the first search request information to obtain multiple word segments, the first target used to represent the fourth location information is determined based on the multiple word segments Word segmentation. When the fourth position information indicated by the first target word segmentation, the second position information, and other word segmentation among the plurality of word segmentation other than the first target word segmentation to form the second search request information, the search gateway may also The downgrade strategy without latitude and longitude performs downgrade processing on other search indication information in the second search request information.

Step 407: The search gateway returns the second service data to the terminal.

In this step, the search gateway sends the cached second service data to the terminal, and the terminal receives the second service data and displays the second service data.

One point that needs to be explained is that when the search gateway does not obtain the service data corresponding to the search request in the cached service data, it can modify the search request repeatedly until the corresponding service data is queried, and the service data is obtained and returned to the terminal , So as to ensure the response rate of the search request sent by the terminal. The search gateway can also modify the search request within a predetermined number of times. After the predetermined number of times is exceeded, the search request is no longer modified, and an error response is directly returned to ensure the validity of the service data returned by the search gateway.

Fig. 6 is a flow chart showing an information search method according to an exemplary embodiment. This embodiment takes the search gateway to execute a downgrade strategy without latitude and longitude as an example for description. As shown in Fig. 6, the information search method includes the following steps :

Step 601: The search gateway receives the first search request sent by the terminal, and obtains the first search request information corresponding to the first search request.

In this embodiment, the first search request information includes at least search indication information provided by the terminal and used to indicate a search target. The first search request information may also include other auxiliary search information used to assist the search.

This step is similar to step 401 and will not be repeated here.

Step 602: The search gateway determines whether to perform downgrade processing on the first search request.

This step is similar to step 402 and will not be repeated here.

Step 603: In response to the need to perform downgrade processing on the first search request, the search gateway queries the cache for the first service data corresponding to the first search request according to the first search request.

This step is similar to step 403 and will not be repeated here.

Step 604: In response to the need to downgrade the first search request and the first service data corresponding to the first search request information does not exist in the cache, the search gateway performs word segmentation on the search indication information included in the first search request information Processing, get multiple word segmentation.

This step is similar to the process of performing word segmentation on the target search indication information in step 405, and will not be repeated here.

Step 605: The search gateway determines at least two second target word segmentation from the plurality of word segmentation according to the weight of each word segmentation.

In this step, the search gateway may determine the weight of each word segmentation according to the amount of information carried by different word segmentation, thereby selecting at least two second target word segmentation that carry a large amount of information. For example, if the search instruction information is "clothing store near street A", the multiple word segmentation obtained by word segmentation are "street A", "nearby", and "clothing store". Meaning, it can be determined that the participles that carry a large amount of information are "street A" and "clothing store", so that "street A" and "clothing store" are used as the second target participles.

Step 606: The search gateway generates the second search request information according to the at least two second target word segmentation.

In this step, the search gateway can directly compose the at least two target word segmentation into the second search request information, and the search gateway can also convert the target word segmentation carrying location information in the second target word segmentation to obtain the fifth location information, and then The second search request information is formed according to the fifth location information and the second target word segmentation.

Correspondingly, in a possible implementation manner, the search gateway splices the at least two second target word segmentation to obtain the second search request information. In another possible implementation manner, the search gateway determines a third target participle representing location information from the at least two second target participles according to the part of speech of each second target participle; according to the third target participle The indicated fifth position information and the target participles other than the third target participle of the at least two second target participles are used to generate the second search request information. This step is similar to the process of generating the second search request information according to the fourth location information, the second location information and the target word segmentation other than the first target word segmentation in step 405, and will not be repeated here.

Step 607: The search gateway obtains the second service data corresponding to the second search request information from the cache according to the second search request information.

This step is similar to step 405 and will not be repeated here.

It should be noted that, in response to the second service data corresponding to the second search request information being absent in the cached service data, the search gateway may perform step 604 again to modify the second search request information. When the second search request information carries the fifth location information, the search gateway may also modify the fifth location information through at least one of the three implementation manners provided in step 404. The third search request information is obtained according to the modified second search request information, until the third service data is obtained according to the third search request information.

Step 608: The search gateway returns the second service data to the terminal.

This step is similar to step 406 and will not be repeated here.
