Search engine that doesn't ignore # . @ special signs

Is there a serch engine that really searchs the things you enter?

For example: Google and many others ignore special characters as well as
the . or # sign.

This is annoying if you want to search for IRC-Channels for example.
A search on #biology will end up with results of the Wikipedia-Entry
Biology as the # will be ignored.

Same with the Search for Band names that contain a . or : in their name,
also if you want to know where you can download .theme files for windows
or the Sennheiser M@B18 headset.

Any search engine that doesn't ignore these signs?
