Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention and the above-described drawings, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, system, article, or apparatus.
The method is characterized in that the index database used for intelligent association and the index database used for content retrieval are two different index databases, and the word segmentation mode and the index used for intelligent association are respectively the same as those used for content retrieval, so that the index database used for intelligent association and the index database used for content retrieval are the same index database. Specifically, how to perform two different searches, namely intelligent association and content search, in the same index database is shown in the embodiment shown in fig. 1.
Referring to fig. 1, the search method in the embodiment of the present invention includes:
101. and acquiring a retrieval request, wherein the retrieval request comprises retrieval characters.
In this embodiment, when the user inputs a character in the search box, the user interface in the search engine initiates a search request to the searcher, where the search request includes the character or character string that has been input in the search box, and is used to request to search the index database for the character or character string. It should be noted that, in the process of inputting characters in the search box by the user, as long as the user interface has not received the click of the search button by the user, it can be confirmed that the user has not input the search word, and therefore, the search request initiated by the user interface at this time is used for requesting the search of intelligent association of the characters or character strings that have been input by the user, so as to recommend the search string that may be of interest to the user.
When the user finishes inputting the retrieval string to be retrieved, the search button is clicked to trigger content retrieval of the retrieval string. After the user interface receives the click of the search button by the user, the user interface can confirm that the user has finished inputting the search word, so that the search request initiated by the user interface is used for requesting the content search of the search word.
102. And judging whether the retrieval request is intelligent association or content retrieval for the retrieval character.
Before the user clicks the search button, the retrieval requests initiated by the user interface are all intelligent association. After the user clicks the search button, the retrieval request initiated by the user interface is to perform content retrieval. In practical application, in order to facilitate a searcher in a search engine to distinguish whether an acquired search request is for intelligent association or content search, a parameter is generally carried in the search request initiated by a user interface to identify a category of the search request. For example, the search request for performing the intelligent association carries the parameter is _ smartbox equal to 1, and the search request for performing the content search carries the parameter is _ smartbox equal to 0.
After receiving a retrieval request sent by a user interface, the retriever judges whether the retrieval request is intelligent association or content retrieval for the retrieval character according to the parameters carried by the retrieval request.
103. When it is determined that the search character is intelligently associated, the search character is searched in a specific field of an index database.
And the searcher searches the index character contained in the search request in the index database after acquiring the search request. Since the search for the intelligent association does not need to be performed in all the fields, but only in a part of the fields, in this embodiment, when the intelligent association is determined to be performed on the search character, the search character is searched in a specific field of the index database.
There are various methods for retrieving a search character in a specific field of an index database. For example, the index of a specific field of the index database is stored in a specific area, and when a search character is searched, the search is performed only in the specific area.
Alternatively, the index of a particular field in the database also contains a particular tag. After the retriever acquires the retrieval request, the specific mark is added in the retrieval character in the retrieval request, and the retrieved content is the same as the retrieval character in the retrieval request, so that the retrieved content contains the specific mark, namely the retrieved content definitely belongs to the specific field in the index database.
Specifically, for example, the search character input by the user is "science and technology limited".
If the word segmentation result of "technology limited" is "technology | limited | company" and "technology limited" does not belong to a specific field, the index of "technology limited" is: "SM science SM finite SM company".
If the specific flag is "\ 0x 3" and "technology limited" belongs to a specific field, then the index of "technology limited" is: "SM science and technology \0x3| SM: finite \0x3| SM: company \0x 3".
Of course, the above is merely exemplary and not limiting.
104. And when the content retrieval of the retrieval character is determined, retrieving the retrieval character in the index database.
When it is confirmed that the search character is to be subjected to content search, the search character is searched in all fields of the index database.
In this embodiment, since the index databases used for performing the intelligent association and the content retrieval are the same index database, waste of storage space can be avoided, and operation cost is reduced, and meanwhile, since the search for the intelligent association does not need to be performed in all fields of the index database, in this embodiment, the search is performed only in specific fields of the index database during the search for the intelligent association, thereby ensuring the efficiency of the search for the intelligent association.
In this embodiment, the specific fields of the index database may be set by default. Optionally, the search engine may also accept user settings for the particular field. For example, on a setting page for a specific field, options for providing a plurality of specific fields selected by a user are displayed, and the search engine determines the specific content of the specific field by accepting the user's selection of each option. Or, 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 a particular field by receiving user input. Of course, the above is merely exemplary and not limiting. After the search engine updates the particular fields, the search engine also updates the index database.
Optionally, in this embodiment, the search engine may further provide two functions of "turn on the intelligent association" and "turn off the intelligent association", and determine whether to turn on the intelligent association by receiving a selection of the user. The present embodiment is executed when the search engine receives the function of "turning on the intelligent association", and only step 101 and step 104 in the present embodiment are implemented when the search engine receives the function of "turning off the intelligent association".
Optionally, in this embodiment, after the search engine searches the search character in the specific field of the index database to obtain the search result, the search engine further obtains a click history of the user on the past intelligent association result, and sorts the priority of the current intelligent association search result according to the click history; and displaying the intelligent association result according to the priority sequence of the intelligent association result.
Specifically, for example, after the search engine obtains the click history of the user on the previous intelligent association results, for the same intelligent association result, the more the previous selection times of the user are, the higher the priority ranking of the intelligent association result is, and the more the intelligent association result is arranged on the display screen.
The above describes the retrieval method in the embodiment of the present invention. The following describes a retrieval apparatus in an embodiment of the present invention.
Please refer to fig. 2, fig. 2 is a schematic structural diagram of an embodiment of a retrieving device according to the present invention.
