Hi, I noticed Hayoo appears as a link in the toolbox of http://hackage.haskell.org and also that Hayoo seems to display better results than Hoogle. For example, if you search for 'PublicKey' in Hayoo, you will get several results from Hackage libraries, such as, 'crypto-pubkey' and 'crypto-api'. However, the same query in Hoogle displays no results. Is Hayoo the default Hackage search engine ? Is Hoogle deprecated ? What the status ? Thank you, Jose

You could also try the Hoogle hosted by FPComplete guys, it indexes more stuff. It's at [1]. I hear that Hayoo actually does a better job getting the relevant results but I am unsure how much truth there is to it. I always thought it was just Hoogle with more indexed docs.

I always thought [hayoo] was just Hoogle with more indexed docs.
Wait - there's a semantic difference: hoogle does understand type signatures (e.g., it can specialize them, or flip arguments of functions) while hayoo just treats signatures as strings (it seems). Example: search for [a] -> [a] hoogle: will also return Data.Text.transpose :: [Text] -> [Text] (note: instantiated a to Text) hayoo: will also return Data.List.isInfixOf :: [a] -> [a] -> Bool (note: the type is [a] -> ([a] -> Bool), so it does actually not contain the type from the query) I much prefer hoogle's query semantics. - J.W. PS: but hoogle also returns inits :: [a] -> [[a]] which is not an instance of the query. Why is this?

Note that the 'normal' hoogle indexes all (?) of hackage. But by default it only searches the haskell platform. You can add a package with '+' to search in that package. E.g. "PublicKey +crypto-api". Regards, Erik

If the idea behind this, that the haskell platform packages should be the first place to look at, than this could be also achieved by sorting the search results. It's a bit pointless, if I have to know the package, where I want to search in. Greetings, Daniel

Yeah! It does sound a bit pointless. Hoogle should search everything by default, and then you can refine your search by clicking on the '+' or '-' on the packages that appear on the left menu.

+1 to this, I never even knew this functionality existed. Why not have a checkbox or something along these lines to enable the search in all packages? This wouldn't change the old behaviour by default and it would allow for a wider search. -- Mateusz K.
Hi,
Hoogle is definitely not deprecated. The reason you can't yet search
all packages simultaneously is that it consumes too many resources -
the number of Haskell packages exploded at a time when I wasn't able
to spend enough time to allow Hoogle to keep up. It's definitely
something on the todo list! The FP complete guys are helping with the
work required to get there.
Be careful what you wish for though. I can't almost guarantee that
every type you search for is available in the lens package as a
hylo-zygote-para-poly-morphism if you instantiate the Bazaar
applicative to the right type. I agree that sorting the platform
packages to the top of the list is likely to help make this more
manageable.
Thanks, Neil
