摘要

PROBLEM TO BE SOLVED: To scalably process mass document indexes and mass user queries. SOLUTION: This device has a user query processing part A-1 which performs morphological analysis of a user query and records it in a shared memory S-1, an object document processing part A-2 which performs morphological analysis of an inputted processing object document, prepares a document index and records it on a document index database D-3, registration query processing A-3 which reads a query content from the shared memory, retrieves it from the document index database and records proper document information on the shared memory when the document information fitting the user query is extracted and a retrieval result processing part A-4 which reads the document information being a retrieval result recorded on the shared memory and outputs it to the user.
