Properly not. I think the problem is that haskell.org do not index
words, that have length <= 3. MediaWiki (which I think haskell.org uses)
do not by default index short words (length <= 3 or length <= 4 - can't
remember which).

If you search for yhc you also get zero results, which does not make
sense either.
