Thread:Project:Support desk/Warning: SQLite is compiled without the FTS3 module, search features will be unavailable on this backend.

I installed sqlite3.

add

extension=php_pdo_sqlite.so

into php.ini

but the mediawiki installer still say: Warning: SQLite is compiled without the FTS3 module, search features will be unavailable on this backend.

I don't use sqlite as database. Must I solve this problem? how to solve it?
