When searching a general topic, you are most likely going to find too much material. For this reason, I suggest you start with one of the directories listed to the right.
Directory services are created by humans, who read the web pages and figure out what they are about. Other searching tools are created by computers which can only look at the individual words on the page and not their meaning.
One nice feature about Excite is that if you find a page you like, you can go back to the Excite listing for that page and choose "Search for more documents like this one" and Excite will do exactly that.
If you don't have much luck, it could be that your subject is better found through your local library. Despite popular belief, the Internet is not the best place to do research on many topics. Go to your local library and talk to a librarian.
