Is it possible to search by partial signature?

I've been enjoying Hoogle a lot, it makes it a lot easier to get acclimated to a new codebase, and it works so quickly too. I've got a common enough issue though, say I'm looking through a library I'm not familiar with and I know I want to use specific type in a function, but I don't know which position in the argument list it is, is there a way to do that?

For example in discord-haskell, I want to learn more about Button. I can search '+discord-haskell ActionRow' (coloring by aft), which'll return something that includes [Button] in its signature

but '+discord-haskell Button' doesn't list that same function:

Is there a way to use wildcards maybe? I looked through the manual and it doesn't seem possible, but it would be nifty to do for sure!

I was effectively hoping to do something like +discord-haskell *Button* or +discord-haskell -> Button to be able to search through function signatures.

Thanks for making Hoogle!

Start with the searching section of README.md and the query examples described in the issue. Trace how Hoogle handles type-signature terms, then define and verify behavior for partial signatures or wildcards; done means a query for Button can find signatures containing it in any argument position, with the supported syntax documented.
