Answer 1

I’m the author and maintainer of pg_search.

Search terms are joined by AND by default in PostgreSQL full text search. Thus, you could simply do this:

 @output = PgSearch.multisearch("filter 1 filter 2")

Assuming you have the query terms in string variables, it would look something like one of these:

 @output = PgSearch.multisearch("#{query1} #{query2}") # if query1 and query2 are strings
 @output = PgSearch.multisearch(queries.join(" "))     # if queries is an array of strings

Joining by OR is a lot more complicated. I don’t yet have an easy solution for it, although it should be possible.
