Yes, we (in Hayoo!) only do text based stuff. Is is possbile to search for 
signatures, but no generalization etc. is done at all. This is very primitive 
in Hayoo! and I really suggest using Hoogle for type searches.

As for the question about a command line interface: There is nothing like that 
for Hayoo!, although one could easily hack something together, just using some 
wget-grep-cut-magic. I also have some code lying around for primitive command 
line searches using an offline Hayoo! index. Maybe I could get that into 
proper shape, given enough public demand ;)
