A search engine and advantages of the indexing and search documents

摘要

The search engine has an indexing module (22) with rapid access storage holding transient incremental data on a small number of documents, and storage (12,14,16; 32,34,36) for the index base which receives contents of the rapid access store. The indexing module forms and stores hash tables from received documents, and computes relevance weightings for elements extracted from documents.
