The options for search are pretty extensive, including token and token prefix queries, phrase queries, NEAR queries, and the usual AND, OR, and NOT queries.Īll queries against SQLite tables take the form of “ MATCH ” in the WHERE clause of a select statement. Now that you’ve created your FTS table, you’re ready to start searching. FTS tables can be used (almost) exactly like any other SQLite table, just with liberal amounts of awesome sauce applied. The difference is you’re creating a virtual table specifying the full-text module you’ll be using.ĬREATE VIRTUAL TABLE book USING fts4 (id, author, title, excerpt) If full-text search is not enabled (you’ll know if creating a full-text virtual table fails), simply recompile, adding the fts3 switches when you do.)Ĭreating an FTS table is about the same as creating a normal table. (While full-text search is not enabled by default, it was enabled in the pre-compiled dll I installed on my Windows machine. Search your full-text table like a boss.Create a new virtual full-text search table.Ensure full-text search is enabled (see below).The first is you don’t need the full-text capability, and the second is you didn’t know it could be done. ![]() Full-text search with SQLite is so ridiculously easy to implement, there are only two valid reasons you haven’t done it yet.
