[0042] Figure 1 FIG. 1 is a flow chart of an information retrieval method according to an embodiment of the present disclosure. Figure 1 As shown, the method includes:

[0043] S101, obtaining a search sentence input by a user, and obtaining the information search requirement of the user according to the search sentence.

[0044] In the disclosed embodiment, a sentence input by the user terminal carrying the user's search requirement can be marked as a search sentence input by the user terminal. The user's search requirement can be parsed through the search sentence input by the user terminal, thereby returning the search result required by the user terminal.

[0045] Optionally, an information extraction algorithm in the related art may be obtained, and the search statement may be algorithmically processed based on the algorithm, and the search requirements of the user end extracted from the search statement according to the result of the algorithm processing may be marked as information retrieval requirements.

[0046] It should be noted that the user terminal may input the search statement in the form of text or voice, and no specific limitation is made here.

[0047] S102, calling the engine capability of the distributed search engine, performing deep paged search of resources based on information retrieval requirements, and obtaining a candidate search result log.

[0048] In the disclosed embodiment, after obtaining the information retrieval requirements of the user terminal, resources can be retrieved based on the obtained information retrieval requirements by calling a preset search engine, and a log consisting of retrieval results obtained by the search engine based on the information retrieval requirements can be marked as a candidate retrieval result log.

[0049] Optionally, a distributed search engine can be called based on the search engine calling method in the relevant technology, and resource retrieval can be performed based on information retrieval needs through the engine capabilities of the distributed search engine, wherein a search keyword can be obtained according to the information retrieval needs, and a deep paged search of resources can be performed based on the search keyword to obtain multiple search results, and the log consisting of the multiple search results can be marked as a candidate search result log.

[0050] The distributed search engine may be an Elasticsearch search engine or any other type of distributed search engine, which is not specifically limited here.

[0051] As an example, the distributed search engine is set to the Elasticsearch search engine. In this example, the Elasticsearch search engine can be called based on the calling method related to the Elasticsearch search engine, and network resources can be retrieved based on the information retrieval system through the engine capabilities of the Elasticsearch search engine to obtain the candidate retrieval result log corresponding to the information retrieval requirements.

[0052] S103, in response to identifying that the user terminal is a first-time access user terminal, obtaining the number of pages corresponding to the candidate search result log according to the number of page display elements of the user terminal.

[0053] In the disclosed embodiment, the candidate search result log may be understood as an information record list consisting of the candidate search results. In this scenario, the candidate search results recorded in the candidate search result log may not be adapted to the user's reading habits.

[0054] Optionally, the candidate search result log may be paged to divide each acquired candidate search result into multiple search result pages, wherein the number of pages limited when the candidate search result log is paged may be marked as the number of pages of the candidate search result log.

[0055] It can be understood that, through the number of pages, the quantity condition that the candidate search result log needs to follow when performing search result paging can be determined, and the paging processing of the candidate search result log can be implemented based on the condition.

[0056] In the disclosed embodiment, the user terminal may be a user terminal in a scenario of first-time access to the server, or may be a user terminal in a scenario of non-first-time access to the server. The strategies for obtaining the number of pages for the user terminals in different access scenarios are different.

[0057] In this scenario, the request parameters for the user's server access can be obtained, and based on the corresponding identification code in the request parameters, it can be identified whether the user is accessing the server for the first time. Furthermore, when it is identified that the user is accessing the server for the first time, it is necessary to obtain relevant information of the user, and determine the number of pages of the candidate retrieval result log corresponding to the user based on the relevant information of the user.

[0058] Optionally, relevant parameters of the display area for the search results provided by the user terminal accessing the server for the first time may be obtained, and the number of pages corresponding to the candidate search result log may be determined according to the relevant parameters of the display area.

[0059] Among them, the display area provided by the user terminal for the search results has a set display area, based on which the number of search results that can be displayed on the display page of the user terminal can be determined, wherein the number can be marked as the number of page display elements corresponding to the user terminal.

[0060] In this scenario, the number of pages of the candidate search result log can be determined based on the number of elements displayed on the page.

[0061] Optionally, the server may also determine the corresponding number of pages based on the relevant information of the candidate search results in the candidate search result log, which is not specifically limited here.

[0062] S104, paging the candidate search result log based on the paging number to obtain a target search page set corresponding to the search statement, wherein the number of pages in the target search page set is the same as the paging number.

[0063] In an embodiment of the present disclosure, the candidate search result log can be paged based on the obtained number of pages to obtain multiple search pages after page processing. The search page can be marked as the target search page corresponding to the search statement, wherein the number of pages of the multiple target search pages is the same as the number of pages.

[0064] Furthermore, based on the multiple target search pages obtained after the paging process, a target search page set of the search statement is composed and returned to the user end for display.

[0065] As an example, each candidate search result in the candidate search result log may be divided based on the number of pages to obtain a plurality of search result subsets after division, wherein each candidate search result included in each subset is displayed on the same page.

[0066] Furthermore, based on the page generation method in the related art, page generation processing is performed on the multiple search result subsets obtained by division, so as to obtain the search result pages of the multiple search result subsets respectively as the target search pages of the search statement, thereby obtaining a target search page set consisting of multiple target search pages.

[0067] The information retrieval method proposed in the present disclosure obtains the information retrieval requirements in the search statement, and obtains the corresponding candidate search result log according to the information retrieval requirements, and then paginates the candidate search result log according to the corresponding number of pages, so as to obtain the target search page set of the search statement. In the present disclosure, the candidate search result log is paginated according to the number of pages to obtain the target search page set. Compared with the related art of obtaining the search results by scrolling query, the abnormal situation that the updated index data cannot be reflected in the search results in the scenario of index data update is avoided, and the situation that the time required for scrolling query affects the real-time performance of the search results is avoided, and the timeliness and real-time performance of the search results are optimized. The search results can be displayed on the user side in the form of paging, realizing the paginated display of the search results and the page jump view of the search results, improving the degree of adaptation between the display form of the search results and the user's reading habits, and optimizing the search experience of the user side.

[0068] In the above embodiment, the acquisition of the target search page set can be combined with Figure 2 Further understanding, Figure 2 FIG. 1 is a flow chart of an information retrieval method according to another embodiment of the present disclosure. Figure 2 As shown, the method includes:

[0069] S201, obtaining a search sentence input by a user, and obtaining the information search requirement of the user according to the search sentence.

[0070] Optionally, a preset sentence parsing algorithm is obtained, and the search sentence is parsed based on the sentence parsing algorithm to obtain parsing information of the search sentence, and the information retrieval requirement of the user terminal is obtained according to the parsing information.

[0071] In the embodiments of the present disclosure, a corresponding sentence parsing algorithm can be obtained based on the form of the search sentence input by the user terminal. When the user terminal inputs the search sentence in text form, a text information parsing algorithm in the related technology can be obtained as the sentence parsing algorithm for the search sentence. When the user terminal inputs the search sentence in audio form, an audio information parsing algorithm in the related technology can be obtained as the sentence parsing algorithm for the search sentence. No specific limitation is made here.

[0072] Optionally, the search sentence may be parsed based on a sentence parsing algorithm to extract the search information carried in the search sentence, and the parsed information may be marked as parsed information of the search sentence.

[0073] Furthermore, by parsing the information, a specific search requirement carried in the search sentence is obtained and marked as the information search requirement input by the user end, so as to achieve accurate extraction of the information search requirement carried in the search sentence.

[0074] Among them, the search statement can be semantically analyzed based on the sentence analysis algorithm, and then the information retrieval requirements in the search statement are obtained according to the analysis information obtained by the semantic analysis. The search statement can also be searched for keywords extracted based on the semantic analysis algorithm, and then the information retrieval requirements in the search statement are obtained according to the extracted search keywords. No specific limitation is made here.

[0075] S202, obtaining a search keyword based on the information retrieval requirement, and performing a deep paged search of resources based on the search keyword through the engine capability of the distributed search engine, to obtain an initial search result log output by the distributed search engine.

[0076] In the disclosed embodiment, a distributed search engine may be called based on a search engine calling method in related technologies, and then a deep paged search may be performed based on information retrieval requirements through the engine capabilities of the called distributed search engine, thereby obtaining multiple search results retrieved by the distributed search engine, wherein a log consisting of the multiple search results is the initial search result log obtained by the distributed search engine.

[0077] Optionally, the information retrieval requirements can be algorithmically processed based on the keyword extraction algorithm in the relevant technology, and then the relevant fields that can be used as keywords in the information retrieval requirements are obtained according to the results of the algorithm processing, and these fields are marked as search keywords in the information retrieval requirements.

[0078] In this scenario, the engine capability of the distributed search engine can be used to perform deep paged retrieval of resources based on the search keyword, thereby obtaining the corresponding initial search result log.

[0079] As an example, a call is set to the distributed search engine Elasticsearch search engine, wherein the search keywords obtained based on the information retrieval requirements can be input into the demand receiving port of the Elasticsearch search engine, and the Elasticsearch search engine performs resource retrieval based on the search keywords received, thereby obtaining an initial search result log consisting of multiple search results.

[0080] S203, sorting the initial search results in the initial search result log to obtain a sorted candidate search result log.

[0081] Optionally, the retrieval time and log line number of each initial retrieval result in the initial retrieval result log are obtained, and the initial retrieval results are sorted according to the retrieval time and log line number to obtain a candidate retrieval result log.

[0082] In an embodiment of the present disclosure, each initial search result included in the initial search result log has its own attribute information, wherein the attribute information may include the time when each initial search result is retrieved, and the time can be marked as the retrieval time, and the attribute information may also include the line number corresponding to the position of any initial search result in the entire initial search result log, and the line number can be marked as the log line number of the initial search result.

[0083] In this scenario, each initial search result can be sorted based on the retrieval time and log line number of each initial search result. Among them, each initial search result can be sorted in the time dimension based on the retrieval time in order from early to late. In the process of sorting based on the retrieval time, there may be a situation where multiple initial search results have the same retrieval time. In this scenario, for multiple initial search results with the same retrieval time, they can be sorted in order from small to large based on the log line number.

[0084] Furthermore, the initial search results are sorted based on the search time and the log line number, and the record log composed of the sorted search results is marked as a candidate search result log, thereby obtaining multiple candidate search results that are adapted to the information retrieval requirements in the search statement input by the user.

[0085] S204, in response to identifying that the user terminal is a first-time access user terminal, obtaining the number of pages corresponding to the candidate search result log according to the number of page display elements of the user terminal.

[0086] Optionally, in response to identifying that the user terminal is a first-time access user terminal, the number of search results in the candidate search result log is obtained, and the number of pages corresponding to the candidate search result log is obtained according to the number of search results and the number of page display elements.

[0087] In the embodiment of the present disclosure, the user terminal may be a user terminal visiting for the first time, or may be a user terminal not visiting for the first time. When the server recognizes that the user terminal currently inputting the search statement is a user terminal visiting for the first time, the corresponding number of pages can be determined based on the number of page display elements of the user terminal.

[0088] As a possible implementation method, the number of search results of each candidate search result in the candidate search result log can be used as the dividend, and the number of page display elements on the user side can be used as the divisor to obtain the quotient of the two, where the quotient can be determined as the number of pages corresponding to the candidate search result log.

[0089] As another possible implementation method, the number of search result divisions of the candidate search result log can be determined based on the number of page display elements, and each candidate search result in the candidate search result log can be divided into sets based on the number of search result divisions, and the number of sets obtained by the division is then determined as the number of pages corresponding to the candidate search result log.

[0090] Optionally, in response to identifying that the user terminal is not a first-time access user terminal, a request parameter of the user terminal is obtained, and the number of pages of the user terminal is obtained from the request parameter.

[0091] In the disclosed embodiment, after the server determines the number of pages of the user terminal, it can put the determined number of pages into a corresponding return parameter and return the return parameter together with the target search page set to the user terminal to mark the number of pages of the user terminal.

[0092] In this scenario, when the user client sends an access request to the server again, the user client can put its marked page number into the request parameter of the server's access request. In this scenario, when the server recognizes that the currently accessing user client is not a first-time accessing user client, it can read the request parameters in the access request sent by the user client, and then read the page number of the user client from the information carried by the request parameters.

[0093] In this way, the accurate acquisition of the paging number of the candidate retrieval result log is achieved. By identifying whether the user end is a first-time user end, different paging number acquisition methods are determined, which improves the efficiency of paging number acquisition, thereby providing accurate paging execution information for subsequent paging processing of the candidate retrieval result log.

[0094] It should be noted that before obtaining the number of paging, it is also possible to identify whether the candidate retrieval result log needs to be paging processed. Here, it can be identified whether the user end has triggered the start condition of the paging plug-in. In response to identifying that the user end has triggered the start condition of the paging plug-in, the paging plug-in is started, and the number of paging is obtained through the paging plug-in to paging the candidate retrieval result log to obtain the target retrieval page set.

[0095] In the embodiment of the present disclosure, the candidate search result set may be paged by a preset plug-in, wherein the plug-in may be marked as a paging plug-in.

[0096] Before starting the paging plug-in, it is possible to identify whether the user terminal needs to display the search results in pages. In this scenario, the relevant information for the user terminal to display the search results can be obtained, and this part of information can be matched with the startup conditions of the paging plug-in. When it is identified that the information matches the startup conditions, it can be determined that the user terminal has been identified as triggering the startup conditions of the paging plug-in.

[0097] In this scenario, when it is recognized that the user end has triggered the start condition of the paging plug-in, the paging plug-in can be started, and the number of pages of the candidate retrieval result log is obtained based on the execution of the paging plug-in, and then the paging of the candidate retrieval result log is implemented based on the number of pages to obtain the target retrieval page set.

[0098] Therefore, by starting the paging plug-in, the paging processing of the candidate search result log is realized, thereby improving the efficiency of the paging processing.

[0099] S205 , constructing a candidate search page set to be filled according to the number of pages, wherein the number of pages in the candidate search page set is the same as the number of pages.

[0100] In the disclosed embodiment, a plurality of display pages to be filled can be constructed based on a preset display page construction method and marked as a plurality of candidate search pages to be filled, wherein the number of constructed candidate search pages is the same as the number of pages.

[0101] Furthermore, based on the constructed multiple candidate search pages, a candidate search page set is formed.

[0102] S206, obtaining the first target search result located at the first position in each candidate search page and each second target search result located not at the first position from the candidate search result log according to the number of page display elements.

[0103] In the disclosed embodiment, after obtaining the number of page display elements, each candidate search result in the candidate search result log may be divided based on the number to obtain a plurality of divided candidate search result log segments.

[0104] The plurality of candidate search result log segments correspond one-to-one to each candidate search page in the candidate search page set.

[0105] In this scenario, the candidate retrieval result located at the first position in any candidate retrieval result log segment can be obtained, and the candidate retrieval result is determined as the first target retrieval result located at the first position in the candidate retrieval page corresponding to the log segment.

[0106] Accordingly, the remaining non-first candidate retrieval results in the log segment except the first one can be obtained, and this part of the candidate retrieval results can be determined as the second target retrieval results that are not in the first position in the candidate retrieval page corresponding to the log segment.

[0107] S207: Fill each candidate search page based on the first target search result and each second target search result to obtain each target search page.

[0108] In the disclosed embodiment, for any candidate search page, the first target search result and each second target search result of the candidate search page can be filled into the candidate search page, and the filled page is determined as the target search page of the candidate search page.

Figure 3 The candidate search result log obtained by the distributed search engine 1 shown in the figure is paginated to obtain Figure 3 The target search page set shown is returned to the user end.

[0126] like Figure 3 As shown, the server may also put the page number of the first-time access client into a corresponding return parameter and return it to the client to mark the page number of the client.

[0127] like Figure 3 As shown, when the client is identified as a non-first-time access client, the number of pages of the client marked by the server in the past can be obtained from the request parameters sent by the client, and the server can query the page number based on the page number.
