It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

The data search method provided in this application can be applied to the application environment shown in FIG. 1 . The terminal 102 communicates with the server 104 through the network. The terminal 102 receives the retrieval request carrying the retrieval keyword, performs an internal retrieval on the preset index database according to the retrieval keyword, obtains an internal retrieval result, and sends the retrieval request carrying the retrieval keyword to the external search engine (ie, the server 104 ), and receives From the external search results fed back by the external search engine, obtain the user history records corresponding to the search request, and sort the internal search results and external search results according to the search keywords, user history records, and preset business ranking information to obtain the target search results. The terminal 102 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

In one embodiment, as shown in FIG. 2, a data search method is provided, and the method is applied to the terminal in FIG. 1 as an example for description, including the following steps:

Step 202, receiving a retrieval request carrying a retrieval keyword.

The search keyword refers to a keyword used to express search intent. For example, the retrieval keyword may specifically refer to a phrase used to express retrieval intention. For another example, the retrieval keyword may specifically refer to a sentence used to express retrieval intention. The retrieval request refers to a request for retrieving a retrieval keyword, and can be operated by a user through a terminal.

Specifically, when the user has a retrieval intention, a retrieval keyword is determined according to the retrieval intention, and a retrieval request carrying the retrieval keyword is sent to the terminal. For example, the user can send a retrieval request carrying a retrieval keyword to the terminal through an input device (such as a keyboard, a mouse, etc.) of the operating terminal. After the user sends the retrieval request carrying the retrieval keyword to the terminal, the terminal can accept the retrieval request with the retrieval keyword. Keyword search request.

Step 204: Perform an internal search on the preset index database according to the search keyword, obtain an internal search result, and send a search request carrying the search keyword to an external search engine.

The preset index database refers to a preset index database, and the index data stored in the preset index database comes from the content crawled by the indexer from the internal database for index establishment. Taking the internal database of the enterprise as an example, the internal database can specifically include the internal document database of the enterprise, the operation database, the user information database, the customer information database, the message database, etc. Different databases have different access methods, such as the internal document database of the enterprise. Search engine crawlers to crawl. The management database, user information database, customer information database, etc. need to connect to the data through the corresponding data interface, and the message database can be directly written into the preset index database based on a certain standard through the agreed format. Specifically, the message log is stored in the message database. It is necessary to obtain the data format in the message database first, then extract the data according to the data format through the intermediate service, store the extracted data in the intermediate table, and finally obtain and extract the data from the intermediate table. to the data. Further, these data sources need to be transformed before they can be stored in the preset index database, and can become objects that can be retrieved by search engines. For example, the conversion method may be: converting the data source into data in the form of key-value pairs, wherein the form of key-value pairs may be in the form of titles and/or abstracts as keys and links as values.

Among them, the internal search result refers to the result obtained by performing internal search on the preset index database according to the search keyword, and the internal search refers to the search within the terminal. By using the internal search to obtain the internal search result, the preset index database can be retrieved. The internal index data is only retrieved and circulated internally, which ensures the security of the internal index data. Taking the data search performed by an enterprise user as an example, the internal retrieval uses a preset index database within the enterprise, and the external search engine refers to a search engine outside the enterprise.

Step 206: Receive the external retrieval result fed back by the external search engine.

Specifically, after receiving the retrieval request carrying the retrieval keyword, the external search engine will also split the retrieval keyword to obtain a plurality of fields to be retrieved, and according to the plurality of fields to be retrieved, the external search engine's own index database is indexed. The data matched to achieve external retrieval, find data matching multiple fields to be retrieved as external search results, and feed back the external search results to the terminal, and the terminal will receive the external search results fed back by the external search engine.

Step 208: Obtain the user history record corresponding to the retrieval request, and sort the internal retrieval result and the external retrieval result according to the retrieval keyword, the user history record and the preset service ranking information to obtain the target retrieval result.

The user history record is used to represent the user behavior. For example, the user history record may specifically be the user history click record, and the user preference feature can be determined through the user history record. The user preference feature is used to represent the user's interest, for example, the user preference feature may specifically refer to which business the user is more concerned about, and the like. The preset service sorting information refers to the preset service sorting priority. The service sorting information can determine which service-related search results need to be ranked first when sorting the internal search results and the external search results.

Specifically, the terminal acquires the user history records corresponding to the retrieval request, determines the user preference features according to the user history records, and sorts the internal retrieval results and the external retrieval results according to the retrieval keywords, user preference features, and preset business ranking information. Get the target search result. Further, the internal search results and the external search results are sorted according to the search keywords, user preference characteristics and preset business sorting information, and the method for obtaining the target search results may be multiple sorting. For example, the multiple sorting may specifically refer to sorting based on search keywords, sorting based on user preference characteristics, and sorting based on preset service sorting information. Further, after obtaining the target retrieval result, the terminal will display the target retrieval result through the display screen.

The above data search method receives a search request carrying a search keyword, performs an internal search on a preset index database according to the search keyword, and uses the internal search to obtain internal search results, so that the internal index data is only searched and circulated internally, ensuring that the internal The security of index data, and at the same time use the retrieval request carrying the retrieval keyword to obtain the external retrieval result from the external search engine, search the internal retrieval result and the external retrieval result at the same time, and obtain the user history corresponding to the retrieval request, according to the retrieval keyword. , user history records and preset business sorting information to sort the internal search results and external search results to obtain the target search results. In the whole process, the search results are output through the internal and external intercommunication of the search results. Due to the internal index data and external index data Both are stored in their respective index databases, and are retrieved in the internal database and external database respectively. Neither the internal index data nor the external index data will fall into different index environments, so it can ensure that the index data is in a safe index environment. It can improve the security of index data.

For example, the link authentication information may specifically be the authentication information that has been issued to the terminal by the external search engine in advance.

Specifically, the terminal will send a link request carrying the link authentication information to the external search engine. After receiving the link authentication information, the external search engine will check whether there is corresponding link information in its own link information database according to the link authentication information. When there is corresponding link information in the information base, it means that the authentication information has been issued to the terminal in advance. If the verification of the link authentication information is passed, the external search engine will feedback the link success prompt to the terminal, and the terminal will receive the link success prompt feedback from the external search engine. After that, the link with the external search engine is successfully established, so that the external search result can be requested from the external search engine by sending a search request carrying the search keyword to the external search engine.

In this embodiment, by sending a link request carrying the link authentication information to the external search engine, when the external search engine passes the verification of the link authentication information, it receives a link success notification feedback from the external search engine, and the link with the external search engine can be realized.

According to the hit keywords of the internal search results and the external search results and the positions of the hit keywords, the internal search results and the external search results are sorted to obtain a first sorting result.

The keywords to be matched refer to keywords obtained by splitting and combining the search keywords. For example, the keyword to be matched may specifically refer to the split retrieval keyword. For another example, the keyword to be matched may specifically refer to a search keyword that is first split and then combined. For example, when the search keyword is a sentence, the keyword to be matched may specifically refer to the fields obtained by splitting the search keyword, or it may refer to the field obtained by first splitting the search keyword and then combining it. each field. Further, when combining fields, the combination can be performed according to a preset proper noun dictionary, and common proper nouns are stored in the preset proper noun dictionary.

The hit keyword refers to a keyword to be matched that appears in the internal search result and the external search result. The position of the hit keyword refers to the position where the hit keyword appears in the internal search results and the external search results. For example, the location of the hit keyword may specifically be the title. For another example, the location of the hit keyword may specifically be an introduction.

Specifically, the terminal will split the retrieval keyword, split the retrieval keyword into multiple fields, and then combine the multiple fields according to the preset proper noun dictionary, and obtain the result according to the multiple fields and the combined fields. For the to-be-matched keywords corresponding to the search keywords, the internal search results and the external search results are matched according to the to-be-matched keywords, and the hit keywords of the internal search results and the external search results and the positions of the hit keywords are determined. According to the preset weight of the hit keyword and the position weight of the hit keyword, as well as the hit keyword of the internal search result and the external search result and the position of each hit keyword, calculate the ranking of the hit keyword in the internal search result and the external search result Score, sort the internal search results and external search results according to the sorting scores, and get the first sorting result.
