searching and hyphenation/spacing

I had mislabelled my backups of Spider-Man and The Weather Man as Spiderman and The Weatherman. It took a really long time to figure out why Spiderman didn't come up in a search. Amazon finds Spider-man from a Spiderman search, but The Weather Man is not found by weatherman, so I would have been lost for much longer if I had tried to add The Weather Man first.

I'm sure it greatly complicates things to "fix" this, but it is one particular instance where the search mechanism seems a bit weak. I'm hardpressed to come up with other examples that don't involve bad english, but try cornerstore versus corner store in books to see the same thing.
