The application also provides a query method, a query device, a target terminal and a medium using the heterogeneous index.

Fig. 2 schematically illustrates a flow diagram of a query method using heterogeneous indexes according to an embodiment of the present application. As shown in fig. 2, the method includes:

s101, acquiring a query instruction, wherein the query instruction carries at least two query fields.

Alternatively, in the present application, a query instruction input by a user may be first acquired. The query instruction carries a plurality of query fields. It should be noted that the content of the query field is not specifically limited in this application, that is, the user may input any query content as the query field, for example, the user may input the query content about the travel class, and the user may also input the query content about the application class. It should be noted that, in the present application, the number of query fields carried in the query instruction is not specifically limited, that is, the number of query fields may be any number greater than two, for example, the query instruction may carry 5 query fields, and the page in the query instruction may carry 15 query fields.

In this application, the device for obtaining the query instruction is not specifically limited, for example, the intelligent device may obtain the query instruction generated by the user, or the server may obtain the query instruction generated by the user.

In addition, in the present application, the smart device is not specifically limited, that is, the smart device may be any smart device, for example, a mobile phone, an electronic notebook, a PDA, and the like.

S102, obtaining at least two corresponding query information based on a preset query strategy and at least two query fields, wherein the query strategy is a strategy for querying by utilizing a plurality of heterogeneous indexes.

Alternatively, in the related art, after the user inputs the query content, the server searches the database for the schema field table corresponding to the query content. The schema field table may be a pre-established relationship table of the query content and a plurality of data information corresponding to the query content. After the server receives the query content, traversing a schema field table related to the query content in an index according to a preset index mode, and after the schema field table is detected, sending a plurality of data information corresponding to the query content as a query result to an intelligent device where a user is located according to the data content recorded in the schema field table so as to be selected and checked by the user. However, with the increasing number of business data, this way of querying data according to indexes requires significant computing resources.

For example, as shown in fig. 3 a-3 c, fig. 3a is information about the commodity a, wherein the name, delivery date, price, model, etc. of the commodity are included in fig. 3 a. Further, fig. 3b is information about a manufacturer that produces the commodity, wherein the manufacturer's name, date of creation, introduction of the enterprise, product management, etc. are included in fig. 3 b. In order to facilitate the retrieval of the user, in the related art, fig. 3a and fig. 3b are generally combined, so as to generate the schema field table as shown in fig. 3 c. And records the schema field table into the corresponding index. So that when the commodity information or the manufacturer information input by the user is received, corresponding data is displayed for the user according to the schema field table.

For example, when it is detected that the user is inputting the query field of the commodity a, the server searches the database for the schema field table corresponding to the commodity a. And obtaining each data information corresponding to the commodity A according to the recorded content of the schema field table.

In addition, in order to avoid the problem of consuming the computing resources of the device, in the present application, after obtaining the query instruction of the user, the corresponding at least two query information may be obtained based on a preset query policy and at least two query fields, where the query policy is a policy of querying by using multiple types of heterogeneous indexes.

The heterogeneous index is an index containing different field characteristics. Wherein the heterogeneous index may comprise a plurality of different types of indexes. In the application, searching of corresponding information can be performed on each query field in the multiple query fields by utilizing multiple types of heterogeneous indexes. It should be noted that the number of heterogeneous indexes is not specifically limited in this application, for example, the number of heterogeneous indexes may be 3, and the number of heterogeneous indexes may be 20.

It is understood that for one query field, in querying corresponding data information using multiple heterogeneous indexes, at least corresponding one query information will be generated. Therefore, after the at least two query fields are queried correspondingly based on the preset query strategy, the corresponding at least two query information is obtained.

S103, generating a query result according to at least two query information.

Optionally, in the present application, after obtaining a query instruction carrying at least two query fields, and obtaining at least two corresponding query information according to a preset query policy and the at least two query fields, a query result may be further generated according to the at least two query information.

It should be noted that, in the present application, after the query information is obtained, the obtained query information may be directly used as a query result, or the obtained query information may be subjected to a preset process, and then the processed information is used as a query result.

Optionally, in an embodiment of the present application, the plurality of types of heterogeneous indexes include at least any two of:

forward index, reverse index, KV index, third party index.

The forward index is a data structure, which can quickly query the attribute of a corresponding document by the name of the document, and the data structure is called the forward index. Further, the inverted index is also a data structure, and with respect to the forward index, the inverted index can quickly find out in which documents a certain attribute or a part of an attribute is in by some attributes of the documents, and this data structure is called the inverted index. Furthermore, the KV index is a data structure for searching data by using a Key-Value (Key-Value) storage database. The third party index is a data structure for searching data by utilizing a plurality of third party databases.

Further optionally, in an embodiment of the present application, in S102 (based on a preset query policy and at least two query fields, obtaining at least two corresponding query information), the method may include any one of the following two ways, to obtain at least two corresponding query information:

the first way is:

and simultaneously, inquiring at least two inquiry fields in the database by utilizing a plurality of heterogeneous indexes to obtain at least two corresponding inquiry information.

Optionally, in the present application, after obtaining a query instruction carrying a plurality of query fields, a plurality of heterogeneous indexes of a plurality of types included in a query policy may be utilized simultaneously to query the plurality of query fields in a database, so as to obtain a plurality of corresponding query information. It is understood that each different type of heterogeneous index generates query information that is different for the same query field. Thus, querying at least two query fields with multiple types of heterogeneous indexes simultaneously in the present application may correspondingly generate multiple query information.

The second way is:

and sorting the heterogeneous indexes of the multiple types in a preset sorting mode.

Optionally, in the present application, after acquiring a query instruction carrying multiple query fields, the heterogeneous indexes of multiple types may be first sorted in a preset sorting manner. It should be noted that, in the present application, the preset ordering mode is not specifically limited, that is, the preset ordering mode may be any ordering mode.

In a possible preferred embodiment, before sorting the heterogeneous indexes of multiple types in a preset sorting manner, a first query field may be parsed first to obtain a first request type, where the first query field is any one of at least two query fields.

Before ordering the heterogeneous indexes of the multiple types in the preset ordering mode, the preset ordering mode can be determined according to the request type of any query field in the multiple query fields.

It will be appreciated that, since the query content input by the user can be various query contents, the variety of the query content is very large. Further, there are different resource search strategies in the face of different types of request queries. For example, when the query content input by the user is music query content, the server may perform only search and recall of the audio resource class. When the query content input by the user is the query content of the website class, the server can only query and recall the website domain name class. When the query content input by the user is the video type query content, the server can only query and recall the video resource type. Therefore, according to different types of the query content, the index types corresponding to the types of the query content can be ranked according to the priority level according to a preset ranking strategy.

For example, the preset policy includes 3 types of heterogeneous indexes. In the application, any one of a plurality of query fields carried in the query instruction may be first parsed. And when the request type of the first query field is detected to be music query content, determining an index mode of searching the audio resource class by using the forward index as the index mode with the highest priority, an index mode of searching the audio resource class by using the reverse index as the index mode with the next highest priority, and an index mode of searching the audio resource class by using the third-party index as the index mode with the lowest priority. Further, the heterogeneous indexes of each type are ordered according to the priority level of each search level. It will be appreciated that in this query strategy, the first order is forward index, second reverse index, and third party index.

For another example, the preset policy includes 2 types of heterogeneous indexes. In the application, any one of a plurality of query fields carried in the query instruction may be first parsed. And when the request type of the first query field is detected to be the text query content, determining an index mode of searching text resource by using the KV index as the highest priority, and searching audio resource by using the positive index as the index mode of the next highest priority. Further, the heterogeneous indexes of each type are ordered according to the priority level of each search level. It will be appreciated that in this query strategy, the order is first KV index and second forward index.

Further optionally, the at least two query fields are sequentially queried in the database by using the sorted heterogeneous indexes to obtain at least two corresponding query information.

Optionally, in the present application, after the heterogeneous indexes of multiple types are ordered in a preset ordering manner, at least two query fields may be queried in sequence in the database according to the ordered heterogeneous indexes of multiple types, so as to obtain at least two corresponding query information.

It can be understood that, in the foregoing preset policy, the 3 types of heterogeneous indexes are included, where the first sequence is a forward index, the second sequence is an inverted index, and the last sequence is a query policy of a third party index, for example, in this application, each query field carried in the query instruction is first queried correspondingly by using the forward index, further, each query field carried in the query instruction is queried correspondingly by using the inverted index, and finally, each query field carried in the query instruction is queried correspondingly by using the third party index.

In one possible implementation manner of the present application, after at least two query fields are queried sequentially according to the sorted heterogeneous indexes of multiple types, a stop instruction may be generated after a first preset number of query information is detected, where the stop instruction is used to stop querying at least two query fields, and the first preset number is an integer greater than 1.

Optionally, after sequentially querying at least two query fields, whether to continue querying the query fields by using the index may be selected based on the obtained amount of query information. It can be appreciated that when the number of the obtained query information reaches the preset value, a stop instruction for stopping querying the query field is generated

In this application, the first preset number is not specifically limited, that is, the first preset number may be 10, and the first preset number may also be 100. The specific variation of the first preset number does not affect the protection scope of the present application.

Further optionally, in an embodiment of the present application, in S103 (generating a query result according to at least two query information), a specific embodiment is further included, as shown in fig. 4, including:

s201, acquiring a query instruction, wherein the query instruction carries at least two query fields.

S202, at least two query fields carried in the query instruction are obtained.

S203, filtering at least two query fields based on a preset filtering rule, and/or performing association processing on at least two query fields based on a preset association policy to obtain query request content.

Optionally, in the related art, after the user inputs the query field, the server searches the data information corresponding to the query field by using the related index, and sends the plurality of data information back to the intelligent device where the user is located, so that the user can select and view the data information. However, when the server searches the corresponding data information by using the index due to the excessively complicated query field of the user, the corresponding data information is difficult to search in the index due to the complicated query field, thereby reducing user experience.

Further, in order to avoid the problem of reducing user experience, in the present application, after at least two query fields carried in the query instruction are obtained, the multiple query fields may be filtered based on a preset filtering rule, and/or at least two query fields may be associated with each other based on a preset association policy, so as to obtain query request content, and further, according to the optimized query request content, data information corresponding to multiple types of heterogeneous indexes may be queried.

It should be noted that, in the present application, the filtering rules and the association policies are not specifically limited, that is, the present application may utilize various filtering rules to filter redundant vocabulary for the query field input by the user, and similarly, the present application may also utilize various association policies to process the associated vocabulary for the query field input by the user.

In a further preferred embodiment, the filtering rule of the term class may be used to filter the redundant vocabulary of the query field input by the user, that is, by detecting whether the term class of the term is included in the query field, and if the term class of the term is included in the query field, filtering the term class of the term in the query field by filtering the term class of the term in the query field to complete filtering the redundant vocabulary of the query field. In yet another possible preferred embodiment of the present application, the present application may use a prefix tree algorithm to perform association processing on the association-type words to generate corresponding well-known words. Namely, whether the query field contains partial words of the known vocabulary or not is detected, and under the condition that the query field contains the partial words of the known vocabulary, the partial words of the known vocabulary are automatically associated into corresponding known vocabulary, so that the processing of the associated vocabulary of the query field is completed.

It should be further noted that, in the process of processing the query field based on the preset filtering rule and the association policy, the processing sequence based on the filtering rule and the association policy is not specifically limited, that is, the query field may be processed based on the preset filtering rule, and then the processed query field is processed based on the preset association policy, so as to generate the query request content. Or, the method can process the query field based on the preset association policy, and then process the processed query field based on the preset filtering rule, so as to generate the query request content.

S204, obtaining at least two corresponding query information based on a preset query strategy and at least two query request contents.

Optionally, in the present application, after processing each query field based on a preset filtering rule and an association policy, and obtaining query request contents, a query result may be further obtained by using multiple types of heterogeneous indexes based on the corresponding at least two query request contents.

In another embodiment of the present application, after obtaining the Query instruction carrying the Query field, query splicing may be performed on the Query field, and after the Query field is spliced, a Query request is sent to the device, so that the device searches for corresponding information from the database according to the spliced field, and the result merging of the Query field is completed, so as to generate the final Query request content. As shown in fig. 5, in the present application, after a feature acquisition stage (FeatureProcess) is performed on a Query instruction to generate final Query request content, query splicing, query request, recall analysis, and result merging may be further performed on the Query request content by using heterogeneous indexes of each type, so as to generate final Query information.

S205, generating a query result according to at least two query information.

In the method, a query instruction carrying at least two query fields is acquired, the query fields are processed according to a filtering rule and an association policy to generate query request contents, and then corresponding query results are obtained based on the query policy and the query request contents. By applying the technical scheme, the query field input by the user can be optimized, and the query result is generated based on the optimized query field and data content corresponding to the heterogeneous index query of a plurality of types. And further, the problem of inaccurate query results caused by inaccurate query fields in the related technology can be avoided, and further, the user experience is improved.

Further optionally, in an embodiment of the present application, after S102 (obtaining the corresponding at least two query information based on the preset query policy and the at least two query fields), a specific embodiment is further included, as shown in fig. 6, including:

s301, acquiring a query instruction, wherein the query instruction carries at least two query fields.

S302, obtaining at least two corresponding query information based on a preset query strategy and at least two query fields.

S303, detecting the quantity of the query information.

It is understood that in the query results in this application, there may be a plurality of corresponding query information. Further, in order to avoid the problem that the user experience is reduced due to the fact that too much information is displayed to the user. According to the method and the device, after the query information is obtained, the query information can be screened out in a targeted mode, and the optimized query information is used as a query result and displayed to a user.

S304, screening out the query information which does not accord with the preset conditions in the query information according to the preset screening conditions when the number of the query information is not lower than the second preset number.

Optionally, after obtaining the query information, the present application may further detect the number of the query information, and determine that the current query information is too many when the number of the query information is detected to be greater than or equal to a second preset number, so that the query information that does not conform to the preset condition in at least two query information may be screened out according to the preset screening condition.

First, it should be noted that, in the present application, the second preset number is not specifically limited, that is, the second preset number may be any number. In addition, in the present application, the second preset number may be the same as the first preset number, and the second preset number may also be different from the first preset number.

Further, in the present application, at least one piece of query information should be retained in the process of screening out the query information that does not meet the preset condition according to the preset screening condition.

In one possible implementation manner of the present application, when the number of the at least two pieces of query information is not less than the second preset number, the screening of the at least two pieces of query information according to the preset screening condition may be accomplished in the following manner:

and detecting query information with the historical click times lower than the preset times in the query information, wherein the historical click times are the times checked by a user in a preset time period range.

Optionally, the application may select to detect that each query information is in a historical time period range, and the user views the displayable data content that has the number of clicked times exceeding the preset number of times. It can be appreciated that the higher the number of historical clicks, the higher the likelihood of query results being truly desired by the user.

It should be noted that, in the present application, the preset times are not specifically limited, that is, the preset times may be 10 times, the preset times may also be 50 times, and the specific numerical variation of the preset times may not affect the protection range of the present application. Similarly, the specific range of the historical time period is not limited, that is, the historical time period range may be within a time range 30 days before the current time zone, and the historical time period range may also be within a time range 100 days before the current time zone.
