Did you rewrite query manually or use rewrite feature of tsearch2 ?

Currently, it's manual. I perform a pg_trgm query for each word of the
search words (a few stop words excluded) and I generate the ts_query
with the similar words instead of using the search words.
Is there any benefit of using rewrite() in this case?

not really, just a matter of possible interesting architectural design.
