Acts as ferret vs mysql full text search

i’ve read that acts as ferret could be faster than mysql for full text
search with many rows.
but is still an option acts as ferret if my search (besides full text
search in 2 or 3 columns) also includes pagination, sorting result,
other conditions (e.g. price > min and price < max, created_at last
week, user_type = admin, show 2nd page, sort desc by price) ?
or if my search contains other conditions besides full text search i
should use mysql?
