SQLite fts3: search for a string in a column


Is there any way to search for a particular string in a column?

I want to search like SELECT * from email_fts WHERE email_fts MATCH 'to:"[email protected]" OR from:"[email protected]"'

Thanks in advance,

Manoj


Solution

  • Make sure you create proper FTS columns in the FTS index:

    CREATE VIRTUAL TABLE email_fts USING fts3(subject, body, "to", "from");
    

    And then you can search individual FTS columns:

    SELECT  rowid 
    FROM    email_fts 
    WHERE   "to" MATCH '[email protected]'
    
    UNION
    
    SELECT  rowid 
    FROM    email_fts 
    WHERE   "from" MATCH '[email protected]'
    

    EDIT: My previous answer had an OR in the WHERE clause. Apparently sqlite doesn't support combining OR queries with MATCH conditions. The above union works.

    FTS docs are here, this is one of the examples used in the docs.
