How do I use it? wat I want to do is search for a phrase then gather as many URL's as possible for that phrase
Their API for this has been closed to new developers. Only developers who had an account before it was closed can continue to use it. Now they're promoting their XmlHttpRequest / AJAX API: http://code.google.com/apis/ajaxsearch/ This could work for you. I personally made a program in C++ which performs searches, parses and saves the URL results.
