Since their categories are narrowed down so much, you will probably find what you're looking for very easily. Yes there are many, but not as many as the spider engines because most people don't know the proper way to submit their site to them. Lycos also has categories. Once MetaCrawler is a meta engine so you can search 6 of the major engines at the same time. It will bring up the most relevant results and neatly tell you which search engine they came from.
ProFusion is also another meta engine to take a look at.
Use Short Phrases When searching try to be specific as possible. Vague words will bring up millions and millions of results. Excite will only list the top ten results if there are too many results. AltaVista will simply ignore all results and you will have to search again using different keywords. This will help narrow down you search and filter out all of the junk.
