I have already wrote you earlier about it. You can solve the problem
by using & (AND), | (OR), and ! (NOT) operators in tsquery.
select to_tsquery('tiger | largest | cat | species') @@
to_tsvector('The tiger is the largest cat');
?column?
----------
t
The query contains one word more than the sentence (the word is
"species"), and it successfully finds it.
