Questions tagged [fts5]

FTS5 is an SQLite virtual table module that provides full-text search functionality to database applications. In their most elementary form, full-text search engines allow the user to efficiently search a large collection of documents for the subset that contain one or more instances of a search term. The search functionality provided to world wide web users by Google is, among other things, a full-text search engine, as it allows users to search for all documents on the web that contain, for example, the term "fts5".
