Substring searches that respect the fact that the particular data its
looking at is CSV? What if the value itself contains commas, will they
be escaped?
I'm thinking of decent genre support, so multiple genre tags per song
(as supported in Ogg). If a song has Song.Genre="Post Rock,Ambient" and
I search for "rock", will the substring search incorrectly match the
song?
