webbase is a crawler for the Internet. It has two main functions : crawl the WEB to get documents and build a full text database with this documents. The crawler part visit the documents and store intersting information about them localy. It visits the document on a regular basis to make sure that it is still there and updates it if it changes. The full text database uses the localy copies of the document to build a searchable index. The full text indexing functions are not included in webbase.
