Ron, it sounds like you're using the Ranked Search, and the results from this type of search are pulled from every conceivable database, and listed in order of best possible match. To narrow your search focus, you should use Exact Search.

You can switch between the two types of search by clicking on either one link or the other at the top of almost every search box, Ranked is a sort of peachy pink colored box, and Exact is a blue box, so if you're seeing peachy pink, look at the top of that box, and click on the words EXACT SEARCH. You should see a significant difference in your results then.

Hope this helps,
Lee
