detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is an embodiment of the invention, but not all of the embodiments. Based on the embodiments of the present invention, those obtained by those of ordinary skill in the art without creative efforts Other embodiments are intended to fall within the scope of the invention.

The terms "comprising" and "having", and any variations thereof, are intended to cover a non-exclusive inclusion, such as a process or method comprising a series of steps or units. The system, product or device is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not explicitly listed or are inherent to such processes, methods, systems, products or devices.

In the embodiment of the present application, the word segmentation method and index used by the intelligent association are the same as the word segmentation method and index used in the content retrieval, respectively, so the index database used by the intelligent association and the index database used for the content retrieval are the same index database. Specifically, how to perform two different retrievals of the intelligent association and content retrieval index database in the same index database, as shown in the description of the embodiment shown in FIG.

Referring to FIG. 1 , an embodiment of the present invention provides a retrieval method, which can be applied to a terminal device such as a personal computer, a tablet computer, or a mobile device, and can also be applied to a network device such as a server. The retrieval method includes steps 101 to 104.

In step 101, a retrieval request is obtained, the retrieval request including a retrieval character.

In an embodiment of the present application, the user may input a character or a character string in a search box of the search engine through the terminal device to perform retrieval of the corresponding content. Each time a user enters a character, the user interface in the search engine initiates a retrieval request to the retriever, which includes a character or string that has been entered in the retrieval box for requesting to look up the character or string in the index database.

In step 102, it is determined whether the retrieval request is an intelligent association request or a content retrieval request for the search character.

In an embodiment of the present application, in the process of inputting characters in the search box by the user, if the user interface has not received the user's click on the search button, it can be confirmed that the user has not completed inputting the search term, therefore, the user at this time The interface initiated retrieval request can be used to request a retrieval of an intelligent association of characters or strings that the user has entered in order to recommend to the user a retrieval string that the user may be interested in.

When the user completes the input of the search string, the search button is clicked to trigger a content retrieval of the search string. After the user interface receives the user's click on the search button, it can be confirmed that the user has completed inputting the search term, and therefore, the search request initiated by the user interface is used to request content retrieval of the search term.

In practical applications, in order to facilitate the searcher in the search engine to distinguish the retrieved search request for intelligent association or content retrieval, the search request initiated by the user interface may carry parameters. The category used to identify the search request. For example, the search request for intelligent association carries the parameter is_smartbox=1, and the search request for content retrieval carries the parameter is_smartbox=0.

After receiving the retrieval request sent by the user interface, the retriever determines whether the retrieval request is an intelligent association request or a content retrieval request for the search character by using parameters carried by the retrieval request.

In step 103, when it is determined that the retrieval request is a smart association request for a retrieval character, the retrieval character is retrieved in a specific field area of the index database.

In an embodiment of the present application, after the retriever obtains the search request, the searcher searches for the search character included in the search request in the index database. Optionally, when it is determined that the retrieval request is an intelligent association request for the retrieval character, the retrieval character may be retrieved only in a specific field area of the index database.

There are several ways to retrieve a search character in a specific field area of the index database. For example, the index of a particular field area of the index database is stored in a particular area, and retrieval is only performed within that particular area when the search character is retrieved.

Or, the index of a specific field area in the database also contains a specific tag. After acquiring the search request, the searcher adds the specific mark to the search character in the search request. Since the retrieved content needs to be the same as the search character in the search request, the retrieved content includes the specific mark, that is, the search The content that comes out must belong to a specific field in the index database.

For example, the search character input by the user is “Technology Co., Ltd.”.

If the result of the word segmentation of "Technology Co., Ltd." is "Technology|Limited|Company", and "Technology Co., Ltd." does not belong to a specific field, then the index of "Technology Co., Ltd." is: "SM: Technology | SM: Limited | SM: the company".

If the specific tag is "\0x3" and "Technology Co., Ltd." belongs to a specific field, then the index of "Technology Co., Ltd." is: "SM: Technology\0x3|SM: Limited\0x3|SM: Company\0x3".

In step 104, when it is determined that the retrieval request is a content retrieval request for the retrieval character, the retrieval character is retrieved in all areas of the index database.

When it is confirmed that the search character is to be retrieved, the search character is searched in all areas of the index database.

In an embodiment of the present application, the index database used for intelligent association and content retrieval may be the same index database, which can avoid waste of storage space and reduce operating costs. In addition, intelligent association can be performed only in a specific field area in the index database, which ensures the efficiency of intelligent association retrieval.

In an embodiment of the present application, the specific field of the index database may be set by default. Optionally, the search engine can also accept user settings for the particular field. For example, an option to provide a plurality of specific fields selected by the user is displayed on a setting page for a specific field, and the search engine determines the specific content of the specific field by accepting the user's selection of each option. Alternatively, an input box is displayed on the setting page of the specific field, and the user can directly input the content in the input box; the search engine determines the specific content of the specific field by receiving the content input by the user. Of course, the above is only an example and is not limiting. After the search engine updates a particular field, the search engine also updates the index database.

In an embodiment of the present application, the search engine may also provide two functions of “turning on the smart association” and “turning off the smart association”, and determining whether to enable the smart association by receiving the user's instruction. When the search engine receives the instruction to "turn on the smart association", the above steps 101 to 104 are performed. When the search engine receives an instruction to "turn off the smart association", only the

above steps

101 and 104 are implemented.

In an embodiment of the present application, after the search engine searches the search character in the specific field area of the index database to obtain the search result, the search engine may also obtain the click history of the user's previous intelligent association result, and according to the click history Prioritizing the sub-intelligent association search results; and displaying the current intelligent association results according to the prioritization of the current intelligent association results.

For example, after the search engine obtains the click history of the user's previous intelligent association results, the same intelligent association result, the more the user selects in the past, the higher the priority ranking of the intelligent association result is, and the display is performed. The more the screen is placed on the front.
