Abstract
A document search method and system for searching and retrieving a document containing a specific character string in response to search requests issued by a plurality of search request sources. When a search request is received in the course of execution of a search processing for an earlier prior search request, the former is stored in a queue buffer. When a plurality of search requests have been stored in a queue buffer in this manner, a search processing is performed for the plurality of search requests simultaneously as stored. The results of search processing as performed are then distributively outputted to the relevant search request sources, respectively. Output buffers for storing a set of search results of the search processings performed in the past may be provided in correspondence to the search request sources, respectively, for screening the documents for which the character string search is to be performed.
