That's odd and I'm not quite sure what's causing that. The hyphens should be ignored in a quoted string at least but they're not. I'll look into it.
Edit:
Actually, I think I see what's happening. The full text minimum word length is currently set to 3. "Yu-Gi-Oh!", despite being one hyphenated word, is indexed as "Yu", "Gi", and "Oh!", none of which are three letters long. I could fix this by changing the minimum word length to 2 I suppose.
