That is pretty much all you need to know to get started with full text searching, but here are a couple other tips. For example, this searches for all books that have the word “cat” in the description: SELECT id, Title FROM BookSearch WHERE Desc MATCH 'cat' With the data in place, you are now able to search it using a SELECT statement with the special MATCH keyword. You can now populate this table with the data you want to search, usually copying it from data in a normal table: INSERT INTO BookSearch SELECT id, Title, Desc FROM Book This creates a “fake” table that is hooked up to the full text search engine. This is done like this: CREATE VIRTUAL TABLE BookSearch USING fts4(id, Title, Desc) With SQLite, you enable full text search by creating what is called a “virtual table” using the fts4 engine. The table has to be scanned row by row to see if it contains the value, which can be slow for large tables.įull text seach is a way to avoid these two issues. Also, using LIKE does not make use of any indexing on the table. For example, you might use this command to find all books that have “cat” in the description: SELECT Title FROM Book WHERE Desc LIKE '%cat%" īut this select actually finds row that has the letters “cat” in it, even if it is in another word, such as “cater”. Without full text searching, you would typically search a text column using the LIKE command.

It is a fast way to look for specific words in text columns of a database table. Resolved Fill a ListBox on XOJO from sqlite rest api.
