Oracle Help includes a full-text search option that enables users to search throughout topic contents. Users have several options such as searching for words based on case-sensitivity, choosing to list only topics containing all the search words, choosing to list only topics containing at least one of the specified search words, and using Boolean expressions. When a user performs a full-text search the results are displayed ranked by relevance, not alphabetically. You can import full-text search databases from other projects using Oracle Help remote views.
