google advance search is also nice using
Domain Restrict
If you know the website you want to search but aren't sure where the information is located within that site, you can use Google to search only that domain. Do this by entering what you're looking for followed by the word "site" and a colon followed by the domain name.
For example, to find admission information on Stanford University's site, enter:
admission site:www.stanford.edu
