Problems solved by technology

Since most large-scale search engines are distributed searches, there are multiple searchers (assumed to be N), and each searcher only saves 1 / N index content, so no matter how you adjust the searcher, you can only sort locally control, unable to regulate as a whole

Embodiment Construction

[0074] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0075] One of the core concepts of the embodiment of the present application is that after each searher end obtains the search results according to the search request, it calculates the aggregation features needed by the merger end in the searher end and returns them in a preset format. The returned search results form a candidate search result set, and the number, position, and proportion of search results with different attributes in each display page are precisely controlled through bucketing and multi-bucket extraction strategies.

[0076] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a search engine sorting method, which may specifically include the following steps: ...

Abstract

The invention provides a search engine sorting method and system and a search engine. The method comprises the following steps: obtaining a candidate search result set, wherein the candidate search result set comprises one or a plurality of search results; dividing the search result or the search results into a plurality of subsets; and respectively extracting search results from the subsets to generate an exhibition page. According to the invention, the global sorting optimization of the research results can be realized, and the quantity, the position and the proportion of one or multiple characteristics are precisely controlled.

Description

technical field [0001] The present application relates to the technical field of data search, and in particular to a search engine ranking method, a search engine ranking system, and a search engine. Background technique [0002] In order to improve search efficiency, current large-scale search engines often adopt a distributed search solution, that is, multiple search servers (searchers) are responsible for the actual search work, and there is also a master control server (merger) responsible for query string parsing. The distribution and the final result are merged. At present, the result merging operation of most search engines on the merger side is very simple. They are based on the scores of the results returned by each searcher. After simple sorting, the top N results are displayed for display. This method mainly has the following two aspects Deficiencies: [0003] On the one hand, most search engines use the expansion method of qurey (search keywords) to combine dif...
