Hi, just replace "AND" and "OR" (used with LIKE operator) for "&" and "|"
(used with to_tsquery).
So this
(content like '%Militant%' OR content like '%jihad%') AND (content like
'%kill%' OR content like '%injure%')
becomes
to_tsvector('english',content) @@ to_tsquery('english', '(Militant |
jihad) & (kill | injure)')
BTW it seems you somehow believe you'll get exactly the same result from
those two queries (LIKE vs. tsearch) - that's false expectation. I believe
the fulltext query is much better and more appropriate in this case, just
don't expect the same results.
