Google search engine uses a technology called PageRank to determine which pages to return as results of a search. First of all, every site on the Internet a gets a rank from 0-10 and is determined by the links to the web site. Each time somebody adds a link to the web site, Google interprets this as a vote for the site. The more links to the site, called "backlinks", the more votes it gets. If it has lots of links from other pages pointing to it, as told by googlebot, it will get a higher pagerank than a site with no links. The higher a page rank, the closer to the first result it will be. So a site with pagerank 10 might have the number one spot, but a site with pagerank 0 may have the 34,403rd spot.

If you are following this, you would recognize that Google may not be the best search engine to find results based on relevancy, proximity and frequency of terms.

Usually the first result is an encyclopedia entry. Notice the "Narrow Your Search" and "Expand your Search" headings on the left side. Another cool feature of Ask.com is the "MyStuff" tab. Use an email address to sign up for an account. Save your searches and specific results in "folders" which can be "shared" with others.
