Document search system

Abstract

Provided is a document search system for collecting desired documents efficiently and intuitively at the time of collecting intended documents using a search system. A list of search results is displayed together with a new search formula candidate and the number of hits obtained by the search formula. Specifically, the document search system includes a related word dictionary having a collection of related words for search key words, a related word search formula generating section which extracts related words for a search key word contained in an inputted first search formula from the related word dictionary, and generates a second search formula using the related words, a search executing section which computes the difference between the number of hits of search results obtained by the first search formula and the number of hits of search results obtained by the second search formula, and a search result display section which displays the first search formula, the search results obtained by the first search formula, the number of hits of the search results, the second search formula, the number of hits of search results obtained by the second search formula, and the difference at the same time.

Description

Technical field [0001] The present invention relates to a document search system, and for example, to a document search system for assisting retrieval of documents of interest from a massive document DB. Background technique [0002] Search technology is a powerful method that is often used. In these search technologies, search is performed by entering search keywords to try to find documents of interest from the massive document DB accumulated on the Internet, intranet, or file server. Internet searches are often performed to collect past findings and related information on a topic for which special documents of interest have not been predetermined. Therefore, the user guesses the search keywords that may return the documents she / he wants, and repeatedly searches to find useful information when arranging the way to input them. On the other hand, for a search on an intranet, a file server, or within a client PC, it is often known in advance that the target document exists, and t...
