Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described below in detail and completely with reference to the accompanying drawings in the embodiments of the present disclosure.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure.

In the related art, there is a problem that the search efficiency is to be improved because a user repeatedly inputs the same keyword into each content server during a search. The content server may include an internal website of an enterprise, and may also include websites of different enterprises. For example, the number of internal websites is increased, and the amount of information is increased with the increase of internal websites of enterprises, so that if employees in an enterprise need to search for some information, all internal websites must be registered to use the search function of each internal website, which may cause the problem of repeated search of the employees in the enterprise on multiple internal websites.

In view of the above, the present disclosure provides a content search method. The method can be applied to a Database System (Database System). Database systems are an ideal data processing system developed to accommodate the needs of data processing. A database system generally consists of three parts: (1) database (DB) refers to an organized, sharable collection of data stored in a computer for a long period of time. The data in the database is organized, described and stored according to a certain mathematical model, has smaller redundancy, higher data independence and easy expansibility, and can be shared by various users. (2) Hardware, including data storage such as memory and/or disk, as needed to store data. (3) Software including a DBMS (database management system), which is core software of a database system and is system software for scientifically organizing and storing data and efficiently acquiring and maintaining data, and a database engine, which is core contents of the DBMS. Each of the content servers providing search contents and the apparatuses collectively providing a centralized search service for a search service in the present disclosure may constitute a database system, and a content search method provided by the present disclosure will be described below with reference to the drawings.

Referring to fig. 1, an application scenario of the content search method provided by the embodiment of the present disclosure includes a user 10, a terminal 11, a centralized search server 12, a content server N1 … Nn, an operation and maintenance person 14, and a terminal 15.

The method can provide a unified search interface, a user only needs to input a search keyword once in a search box of the interface, a centralized search server interacting with the interface can distribute a search request to each content server with access authority according to an access address, and after the content server searches according to the access authority of the user, a search result is returned to the centralized search server and returned to the terminal by the server. Therefore, the terminal can obtain the search results with access rights in the plurality of content servers.

For example, the user 10 may input a search keyword through the unified search interface on the terminal 11, and may select a certain number of content servers to search at the content server N1 … Nn. The terminal 11 generates a search request according to an operation of a user and transmits the search request to the centralized search server 12. The centralized search server 12 searches the access addresses corresponding to the selected content servers from the access address list, and distributes the search request to the corresponding content servers through the addresses.

After receiving the search request, the content server searches the server. The search results that the user 10 has access right are returned to the centralized search server 12.

Then, the centralized search server 12 sorts the results returned by all the content servers according to the scores of the search results, and returns the sorted search results to the terminal 11 for display. Thus, the user 10 can obtain a final search result through the terminal 11.

Wherein the terminal 11 and the centralized search server 12 can be communicatively connected through a communication network, and the centralized search server 12 and the content server N1 … Nn can also be communicatively connected through a communication network, which can be a local area network, a wide area network, etc.

The terminal 11 may also be referred to as a User Equipment (UE). The user equipment can be a smart phone, a tablet computer, various wearable devices, vehicle-mounted devices and the like. Various applications may be installed in the user device, such as a camera, a browser, and so on.

The centralized search server 12 and the content server N1 … Nn may be any server device capable of supporting the processing of the corresponding databases.

In implementation, the content server access address may be configured by the operation and maintenance personnel 14 through the terminal 15, and the configuration result may be stored in the access address list. In one embodiment, registration may be based on a service registration page as shown in FIG. 2. Fig. 2 is a schematic diagram of a service registration page according to an embodiment of the disclosure. Referring to documents of the search system for implementing the service interface, the content server provides a service including multiple development languages of the specified interface. The service will provide an interface whose key parameters include: search keywords and user identification such as Token(s) that initiated the search, the user identification representing the access rights of the user; the return value is a search result in a specified format and may include 0 to a plurality of pieces.

When a new content server is added, the service address of the multi-development language service and the corresponding content server identification of the content server can be written into the corresponding input box of the page in the service registration page, and then the centralized search server can acquire the multi-development language service registered in the service registration page in real time.

In addition, in combination with the display diagram of the service registration page of the content search method according to the exemplary embodiment of the disclosure shown in fig. 2, in order to avoid confusion of information, it should be noted that the names of the content servers are not repeated during registration.

In the method, the multiple development language service is, for example, a gRPC service (Google Remote Procedure Protocol), and the gRPC service is a high-performance and strong-versatility RPC (Remote Procedure call) open-source framework, and is mainly developed for mobile applications and can be used as the multiple development language service.

After the content server is registered, the present disclosure provides the unified search interface as described above as a front-end application of the search system, as shown in fig. 3, which is a relationship example between the interface of the unified search interface and each internal website interface in the related art, where the internal website interfaces are two interfaces, i.e., "internal news web" and "internal forum" in fig. 3. The unified search interface is equivalent to the function of realizing the access interface of each internal website. In fig. 3, the unified search interface includes a plurality of content server identifiers having access rights, and further includes an input box for a user to input a search keyword. For example, the content server identification includes: an internal news web, an internal forum, an internal shared document, and an internal encyclopedia. If the user selects the internal news web and the internal forum, the search for the "company profile" keyword is performed. The method is equivalent to the search operation of repeatedly inputting the company brief introduction in the internal news network and the internal forum respectively. Because the centralized search server distributes the search request about the company profile to the respective servers of the "inside news web" and the "inside forum" to complete the search, the centralized search server distributes the search request, and the user is unaware. Thereby achieving the purpose of simplifying the operation of the user.

In addition, the unified search interface comprises the identifiers of the various content servers which can be selected, and a user can set which content servers to search in based on own requirements. Moreover, each content server is searched based on the access authority of the user, so that the fed back search result is more accurate.

In the above method, the authentication of the user may be completed before the search request is sent to each content server. For example, the login authentication is implemented by the user sending login identity information to the unified authentication platform through the terminal 11 for login authentication; and then the unified authentication platform sends the user login credentials to a centralized search server or a terminal after authentication, and then the centralized search server sends the user login credentials to each content server so as to facilitate the content servers to determine the access authority.

In one embodiment, a portal for entering login identity information may be provided in the interface shown in FIG. 3. For example, when the user equipment sends a request for logging in the same search interface, the background jumps to the authentication interface and is displayed by the user equipment. And after the user inputs login identity information on the authentication interface and completes authentication, the user equipment displays the unified search interface shown in the figure 3. At this time, the identifiers of the content servers displayed in the unified search interface are the identifiers of the content servers with the access right of the user. That is, the content server identifier of the unified search interface viewed by the users with different access rights is the identifier of the server with access rights.

In one embodiment, the entry to the authentication interface may also be provided in the unified search interface, as shown in fig. 3, and the content server identifications may be in an inoperable state prior to authentication. The login interface can be entered through a "login" control as shown in fig. 3 to complete the input of login identity information to achieve user authentication. Of course, when the identity information is not logged in, the user can completely register through the "register" control in the interface shown in fig. 3. The login identity information may include a user name and a password, or include a employee number and a corresponding password. Of course, in specific implementation, the parameters included in the login identity information may be set according to actual requirements, as long as the parameters can be used for verifying the access right.

After obtaining the user login credentials based on the user identity information, referring to fig. 4, a schematic flow chart of a content search performed by the centralized search server according to an exemplary embodiment of the present disclosure may include the following steps:

step 401: receiving a search request sent by a terminal, wherein the search request comprises a search keyword and a user identifier;

step 402: searching access addresses respectively corresponding to the content servers in the access authority corresponding to the user identification from an access address list;

step 403: distributing the search request to a corresponding content server through the access address;

step 404: and receiving the search results returned by the content servers and returning the search results to the terminal for display.

The content searching method can integrate the searching pages of all the content servers into one unified searching interface, and can realize content searching in a plurality of content servers only by inputting keyword searching once. Moreover, the content server meeting the requirement of the user can be independently selected from the registered content server access list in the unified search page, and then the centralized server can find the access address of the content server selected by the user and send a search request to the content server. Therefore, the content searching method can greatly improve the searching efficiency of the user among the content servers and reduce the repeated development work of the searching page of the content server.

Referring to fig. 5, a timing diagram of a content search method according to an exemplary embodiment of the disclosure, which can be further explained, includes the following steps:

step 501: and the terminal sends login identity information to the unified authentication platform.

Step 502: and the unified authentication platform authenticates the login identity information, and if the login identity information passes the authentication, a Token is generated and sent to the terminal.

Step 503: and the terminal sends a search request to the centralized search server and carries Token.

After obtaining the search request, the centralized search server first accesses the unified authentication platform to verify Token validity, and if Token validity is valid, the centralized search server continues to process the search request, that is, step 504 is continuously executed.

Step 504: and the centralized search platform acquires a gPC service list which is currently registered.

Step 505: distributing the search request to a content server selected by the user;

after receiving the search request, each content server firstly sends Token verification to the terminal; after the Token effective information is obtained, because the Token corresponds to the user one by one, the content server can uniquely determine the corresponding access user according to the Token so as to determine the access authority of the access user. In addition, the content server searches according to the search keyword, and after obtaining the search result, filters out the search result that the user does not have the access right, and then executes step 506.

Step 506: each content server returns the search result to the centralized search server;

step 507: and the centralized search server returns the sorted search results to the terminal.

In the method, each search result has a corresponding score, and the centralized search server can sort the search results according to the scores, wherein the scores of the search results are higher when the click quantity of the user is larger in the search results aiming at the same keyword.

For example, in practice, the centralized search server may maintain a search result score table, and the key values in the table may include the search keywords and the scores of the search results corresponding to the search keywords. For different keywords, there may be an intersection of their search results, e.g., search result a1 for keyword 1 in table 1 and search result B1 for keyword 2 in table 2 are the same search result. However, in the case of keyword 1, the score a1 of the search result a1 is higher than the score B1, i.e., the click volume of the same search result under different search keywords is different, and thus the score may be different. In implementation, the scores corresponding to the search results of the corresponding search keywords need to be sorted.

TABLE 1

TABLE 2

By sequencing the search results according to the scores, the search results closely related to the search keywords can be obtained, and the user can select to view the search results according to the degree of correlation with the keywords and the requirement of the user. In addition, the same search result may correspond to a plurality of search keywords.
