Translates to the underlying SQL LIKE query, therefore
its behaviour is dependent on the database. In particular,
PostgreSQL will do a case-sensitive operation, while the
majority of other databases will be case-insensitive. For
performing a case-insensitive like
in PostgreSQL, see ilike/2
.
You should be very careful when allowing user sent data to be used as part of LIKE query, since they allow to perform LIKE-injections.
