Embodiment Construction

[0045] The technical scheme of the present invention layers multiple search strategies, and sorts each layer of search strategies within a block, so as to generate a search strategy matrix according to the priority level. In addition, various real-time sorting factors are added to the sorting in the form of plug-ins In the strategy, the real-time performance of sorting the search result set is realized.

[0046] figure 1 Shown is the basic flow of the embodiment of the present invention, including the following steps:

[0047] Step 101: Generate a search strategy matrix: select more than one search strategy according to the requirements of the search service, and generate a strategy matrix for the selected search strategies according to their priorities.

[0048] Step 102: Divide search result blocks: Divide according to the number of rows of the search strategy matrix, each row corresponds to a subset of search results.

[0049] Step 103: In-block sorting of search results:...

Abstract

The invention provides a method for sequencing search results. The method comprises the following steps: firstly, generating a search strategy submatrix for each searching item, wherein each row in the search strategy submatrix corresponds to a search strategy layer; the priority weights of different search strategy layers increase or decrease progressively in sequence; and the priorities of the search strategies on the same search strategy layer are same; secondly, selecting at least a search strategy from each search strategy layer of the search strategy submatrix to assemble a query set, matching the query sets with all searched files according to the search strategies and multiplying the file scores by the priority weights corresponding to the search strategies to obtain result set objects; and selecting the result set objects and assembling the selected result sets to form a complete result set. The method has the following beneficial effect: the sequencing accuracy of the search result sets is ensured by the following steps: generating the search strategy matrix by using various search strategies, carrying out data domain division on the search result sets and then assembling the search result sets.

Description

technical field [0001] The invention relates to the technical field of computer internet, in particular to search engine technology, and in particular to a method and device for sorting search results. Background technique [0002] Currently commonly used search engine sorting methods are generally based on comprehensive scoring of the relevance of search keywords in documents, and sort the searched document sets according to the scores. Taking the Lucene sorting method as an example, the document score has a specific calculation formula. Factors that affect the score include the frequency of search keywords, the length of each document, and the coverage of search keywords in all documents. Due to the relatively small score gap between documents, it is difficult to meet the requirements of precise sorting according to the strategy level; the comprehensive document scoring method does not take real-time data into consideration as parameters, such as the number of user clicks,...
