Signatures lacking spaces return generate no query

[gabejohnson]

Typing a->b->a into the search bar returns a list of unrelated results. I would expect the same results as a -> b -> a (a list of results headed by const).

I'm guessing delimiting on -> or inserting spaces would fix this.

Thanks for the report. I deliberately allow identifiers to contain - in them as during the lexing I might be expecting a package name. To fix that, I demand that - can't be the end of an identifier, so it should work now.
