I don’t know how pervasive this is, but when I tried searching for the Album “O.M.G.!” I got no results. Thought it a quirk, that maybe Jaikoz didn’t search all fields (including Album), and searched by the artist of said album instead.
Later, tried searching for AC/DC and again got not results, despite knowing that I have AC/DC in full view. 
The only thing tying the two is the use of symbols, so it’s just a guess but I’m betting it’s a safe one.
