Three-segment sequential collecting method and system for retrieval results

Abstract

The invention discloses a three-segment sequential collecting method and a three-segment sequential collecting system for retrieval results, and belongs to the technical field of retrieval. The conventional collecting mode needs to occupy a large amount of memory space at many retrieval results, and has low sequencing performance. The method comprises the following steps of: performing retrieval according to a retrieval request and acquiring the retrieval results; then collecting the sequenced front part of the retrieval results in a head segment according to the predetermined capacities of the head segment, the tail segment and the middle segment, collecting the sequenced last part in the tail section, and collecting the sequenced middle part in the middle segment; and finally, returning the retrieval results from the head segment, the tail segment and / or the middle segment according to a retrieval result returning request. The method and the system can effectively reduce the storage space of the retrieval results, enhance the sequencing performance of the retrieval results, and comprehensively improve the integral performance of a retrieval system.

Description

technical field [0001] The invention belongs to the technical field of retrieval, and in particular relates to a three-stage orderly collection method and system for retrieval results, and is particularly suitable for the orderly collection of full-text retrieval results. Background technique [0002] After the full-text retrieval system searches according to the retrieval request, it also needs to sort the retrieval results, and then return the ordered results within the range specified by the user. The sorting basis is usually the correlation between the search result and the search request, and may also be other basis, such as the importance of the search result, the order of a field value of the search result, and so on. The purpose of sorting the retrieval results is to make the results that best meet the user's needs appear at the top of the result sequence. [0003] The front desk of the full-text retrieval system generally displays the retrieval results in pages, an...

Problems solved by technology

[0004] The follow-up processing of the retrieval results of the full-text retrieval system brings performance problems: with the increase of the amount of data processed by the full-text retrieval system, when a large number of results are hit, the storage and sorting of the retrieval results will occupy a large amount of storage space and processing time. The retrieval performance is poor, and the retrieval results cannot be processed quickly and concurrently.

The disadvantages of this method are: a large amount of storage space is required, and the sorting performance of a large number of results is low

When the search result range requested by the user is at the end of all search results, it becomes to collect all search results. At this time, the storage space is the same as the first method, and the performance is lower due to all sorting

[0013] Both of the above two existing methods need to save a large number of retrieval results, thus occupying a large amount of memory space, and when there are many retrieval results, the sorting performance is low, which makes the performance of the full-text retrieval system drop
