[Haskell-cafe] Hoogle index completeness

  Hi Alvaro,

by default Hoogle only searches some standard set of packages, which is
only a relatively small subset of all Hackage content. From
http://www.haskell.org/haskellwiki/Hoogle#Scope_of_Web_Searches :

> Using the standard web interface, Hoogle searches: array, arrows, base,
bytestring, Cabal, cgi, containers, directory, filepath, haskell-src,
HUnit, mtl, old-locale, old-time, packedstring, parallel, parsec, pretty,
process, QuickCheck, random, stm, template-haskell, time, xhtml.

See http://www.haskell.org/haskellwiki/Hoogle/Packages

One solution is to install Hoogle locally and let it index all packages you
have installed.

Best regards,
Petr
