sqliteHow can I implement full text search in SQLite?
Full text search in SQLite can be implemented using the FTS3 and FTS4 extensions. FTS3 and FTS4 are virtual table modules that allow users to perform full-text searches on a set of documents. FTS3 is an older version of FTS4, but both provide similar functionality.
Example code
CREATE VIRTUAL TABLE documents USING fts4 (content TEXT);
INSERT INTO documents VALUES ('This is an example document.');
SELECT * FROM documents WHERE documents MATCH 'example';Output example
This is an example document.The example code creates a virtual table using the FTS4 module, inserts a document into the table, and then performs a full-text search on the table using the MATCH operator. This example returns the document that contains the word "example".
The FTS4 module provides several useful features for full-text search, including the ability to specify the language of the documents, the ability to perform phrase searches, and the ability to perform fuzzy searches.
