Abstract
A computer based system and method of retrieving information pertaining to electronic documents on a computer network is disclosed. The method includes maintaining a database that associates each electronic document with a corresponding crawl number that indicates the most recent crawl during which a change to the document was detected. During a subsequent crawl, electronic documents that have changed since the previous crawl are retrieved, and selected data is stored in a database. The retrieved document information is marked with a crawl number. During subsequent searches, crawl numbers are used to determine documents that have changed since a specified crawl.
