Does Hoogle let you search by example?

  It lets you search by type signature. If you know the inputs and output then you know the type signature. So in short, yes. Edit, example: https://www.haskell.org/hoogle/?hoogle=Char+-%3E+Char https://www.haskell.org/hoogle/?hoogle=Char+-%3E+Char

      Searching by type signature is very useful. I think searching by example input and output pairs would be a great addition to Haskell as well, especially for beginners and the base libraries. A technique I use for poorly documented libraries is searching in github '<some keywords> <optionally library name> language:<language>'. Unfortunately there are some serious limitations in github search, no way escape certain characters.

      In short, yes. You give it an example of the types involved. Instead of "hi" -> "HI" you give String -> String.
