I was just experimenting with searching for spells, and noticed something. If I search for "Fireball" (the proper spelling of the spell), the spell comes up just fine; however, if I search for "Fire ball", it doesn't.

I know that on the surface this doesn't seem like a huge deal. I'm a bit of a pedant, and stickler for proper spelling myself, but I know several players who aren't. It would be nearly impossible to guess every misspelling and permutation of every spell's name out there. However if there were searchable keywords, a search for "Fire ball" would likely hit one (if not two) of Fireball's. This would also help a new convert from an earlier edition who may try to look up "Tenser's Floating Disk" (fails), or even someone who knows the new name, but can't remember if it's "Floating Disk" (works) or "Floating Disc" (fails). If the keyword "Floating" is attached to the spell, though, it should come up in the results for the user, rather than a completely blank result.

I'd extend this to monsters and items as well (especially the plethora of magic items). I know this is a ton of extra work on the back end, but I'm pretty confident that the added utility and lack of frustration it will create on the client side will make it worth it.
