Good to hear from you again, B.B. Narrowing internet and web searches can be quite an art, but anyone can become proficient with a little practice. Perhaps the most obvious way to begin is to be as specific as you can be about what you're looking for. If you're searching for an exact phrase, most search engines allow you put the phrase in quotes so that you only return results that exactly match your entire phrase. This should narrow your search considerably. Every search engine has its benefits and drawbacks, though.
Some engines are quite indiscriminant about what sites they index, while others are quite picky.
All web search sites have information on the best way to use their engines, and there are also at least a dozen books that reveal the secrets of the best searchers.
