Method for presenting search results

Abstract

Methods and systems are provided to present the search results in response to a search query that is submitted to a document retrieval system, such as a search engine. The search results are presented with a second-retrieval model that constructs multiple derived queries for the search query with a first small-document retrieval process, and then generates and outputs the results based on the retrieval of search results of at least part of the derived queries. One embodiment of the invention provides a method for grouping the search results, which presents ranked derived queries together with their search results to the user, in such a way that derived queries with higher ranks and top-ranked documents of each derived query are preferentially presented, and the grouped results are displayed and navigated in independent framed subareas of an output window. A further embodiment selects the search results from multiple result lists of the derived queries to form the final search results for the user query, wherein the merged results are re-ranked according to pre-determined criteria. The method can also be integrated with the local keyword associated clustering method by rank value adjustment, or result filtering or merging to achieve better technical effects.
