Lynn, I think nobody of us knows perfectly what the best search strategy is.
A maid in Bedlam doesn't find it [A maid in Bedlam] does Maid in Bedlam doesn't [Maid in Bedlam] does maid bedlam does

If you don't use the [] the theoretical idea is that the search engine finds all songs with these words in it irrespective of the position of these words. Obviously that isn't true, see the above examples. My advice is, never use words that appear in nearly all songs (like a, in) exept in a [phrase]. Mostly this advice works, but I don't know why.
