Thank you for your reply.

http://www.haskell.org/haskellwiki/Hoogle#Database_Creation

Hoogle needs database file to search packages' API.
A textual database file (foo.txt) can be created by haddock --hoogle command.
And we need to convert textual database to binary database by hoogle command.

  package foo =haddoc=> foo.txt =hoogle=> foo.hoo

Hoogle can search above binary database (foo.hoo).
But today, hoogle can't create foo.hoo file, because libghc-*-doc package
don't have any foo.txt file.
It's a problem on Debian.

Can I apply below patch to haskell-devscripts?

+DEB_HADDOCK_OPTS += --hoogle
 ifndef DEB_NO_IMPLICIT_HADDOCK_HYPERLINK
 DEB_HADDOCK_OPTS += --hyperlink-source
 endif

The patched haskell-devscripts will create libghc-*-doc packages.
The libghc-*-doc package have foo.txt file.
In future, my hoogle package will collect textual database files installed,
and convert them to binary database files.
