A search method and device

Abstract

Embodiments of the invention disclose a search method and apparatus. The method comprises the steps of receiving a search request sent by a client, wherein the search request comprises a search word input by a user through the client; performing a search according to the search word to obtain an initial search result set; performing word segmentation processing on the search word; performing matching on segmented words obtained by the word segmentation processing in a preset classified lexicon, thereby determining a lexicon type hit by the search word as a target lexicon type; increasing a weight value of the target lexicon type; readjusting the initial search result set according to the increased weight value of the target lexicon type, thereby generating a final search result set; and returning the final search result set to the client, thereby displaying the final search result set to the user. The weight value corresponding to the search word of the user can be adjusted according to a search intention of the user, so that search results better meeting real demands of the user can be preferentially displayed to the user.

Description

technical field [0001] The present invention relates to the field of search technology, in particular to a search method and device. Background technique [0002] A vertical search engine is a professional search engine aimed at a specific field, a specific group of people or a specific need. It is a subdivision and extension of a search engine. The field extracts the required data for processing and then returns it to the user in some form. [0003] At present, the vertical search engine uses the search keywords entered by the user to calculate the scores of relevant documents according to the rules of full-text search and matching, and then outputs the search results to the user in order of scores from high to low. However, this method only displays the search results to the user according to the optimal order that the system thinks, and does not care whether the order of the search results meets the real needs of the user. When there is a gap between the ranking of sear...

Problems solved by technology

However, this method only displays the search results to the user according to the optimal order that the system thinks, and does not care whether the order of the search results meets the real needs of the user.

When there is a gap between the ranking of search results and the real needs of users, the search results that users really want will not be displayed to users first, thus affecting the search conversion rate and click-through rate

For example, in the field of real estate, when users search for specific categories of words such as cities, districts and counties, or developer names, if the ranking of search results of vertical search engines is different from the real needs of users, on the one hand, users will not be able to quickly search for words. Find the real estate information you need, on the other hand, it also affects the rental or sale of the real estate
