Yes.

Only for queries involving text indexes, and even then it's not very
meaningful.  It takes the entire batch of search results, from the most
relevant (word occourance score) the the least relevent, and normalizes
all their scores between 0 and 100 (or 0 and 1, same difference).

Yes, You would have to fetch the object and then scan it for the search
terms.
