To enter a query, select either the "web" or "this site" radio button. Then, just type in a few descriptive words and hit the 'SEARCH' button for a list of relevant results. The search only returns web pages that contain all the words in your query, refining or narrowing your search is as simple as adding more words to the search terms you have already entered.
