1 Comparison operation for tsquery 2 Btree index on tsquery 3 numnode(tsquery) - returns 'length' of tsquery 4 tsquery @ tsquery, tsquery ~ tsquery - contains, contained for tsquery. Note: They don't gurantee exact result, only MAY BE, so it useful only for speed up rewrite functions 5 GiST index support for @,~ 6 rewrite(): select rewrite(orig, what, to); select rewrite(ARRAY[orig, what, to]) from tsquery_table; select rewrite(orig, 'select what, to from tsquery_table;'); 7 significantly improve cover algorithm
