Embodiment Construction
[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0055] If the search results are closer to the user's search needs, the sorting must take into account as many features as possible of a certain category of shopping sites. In this way, if the commodities are classified, a separate sorting model can be established according to the characteristics of each category of commodities, and the commodities of each category can be sorted separately. Then, on the search results page, display by category can make the search results closer to the user's search needs. However, the total number of categories affects the effect of the above sub-category display methods, because if there are too few or too many categories, it will be difficult for the front end of the search engine to find a frie...

The invention provides a search method and a search device. The search method particularly includes acquiring search results of classes of searched objects according to a search query request; respectively sorting the search results in various classes according to cross-class sorting features and internal sorting features of the various classes to obtain a cross-class sorting feature value of each searched object and a classified sorting result; mixing and sorting the search results according to the cross-class sorting feature value of each searched object and the classified sorting result, arranging the searched object with the largest cross-class sorting feature value in a mixing and sorting result in front of searched objects with small cross-class sorting feature values, and enabling the relative position of each searched object in the mixing and sorting result to be identical to the relative position of the searched object in the classified sorting result; and returning the mixing and sorting result as a search result to a user. The search method and the search device have the advantages that the sorting result can effectively meet search requirements of the user, burden on a server is relieved, and occupied network bandwidth resources are reduced.
Description
technical field [0001] The invention relates to the technical field of search engines, in particular to a search method and device thereof. Background technique [0002] At present, in the face of a large number of shopping websites, search engines generally first use crawlers to capture the commodity information of these shopping websites into their own databases for storage. Because different types of shopping websites have different characteristics, generally, an excellent search engine will capture all commodity information reflecting the different characteristics of these shopping websites. For example, the timeliness of group buying websites is very strong, so it is necessary to capture the online time of group buying products; After-sales protection is more concerned, so it is also necessary to capture relevant information about after-sales services. After the captured product data is processed offline, the search engine can build an index for the processed product ...
