Re: [Haskell-cafe] Hayoo and Hoogle (beginner question)

I had heard that Hoogle actually compiled any type-signatures, where as Hayoo just did a text comparison.

I'm not actually sure if this is true or not though.

If it is, it would mean that "[q] -> [r] -> [(q,r)]" would return zip in Hoogle, but not Hayoo.

Am I right about this?

You are right: http://haskell.org/hoogle/?hoogle=[q]%20-%3E%20[r]%20-%3E%20[%28q%2Cr%29] But Hayoo searches all of hackage while Hoogle also searches a lot, but not all. If I'm searching for a function that is probably in base or containers, I use hoogle. Otherwise I use hayoo. In short: They are both very useful.
