I mean there's nothing in particular to optimize. Outside of exact title matches, results are unpredictable.
Well, maybe I worded myself wrong. The point is, that I wanted my game to show up on the list when someone searches for "hex puzzle", and it didn't show up on the list. Now that I changed the title to what I mentioned earlier, it does show up. So there in fact was something I could do - call it optimization or not.
