I was wondering if there is a tool or a step-by-step way to do a
certain successful search on Google or any other search engine that has
many indexed pages? What I mean is to be able to search for a keyphase
in the actual cached html/text files. For example if I want to find
all the indexed pages with '<meta name="keywords" content="apples' or
'<script>var txt = "Bookmark Us!"' it would produce all the matching
results. I would need to be able to search for keyphases embeded in
the source code such as scripts, that don't show up on a normal
search or browser.

I found a site http://www.marketing-ideas.org/keyword-suggestion-tool.php?I=199888052&T=731713
about half way down you will see this: Peak under the hood of your
competition

"The first keyword marketing strategy is to "peak under the hood" --
literally visit dozens of the top-listed Web sites at Google? for the
keyword or phrase similiar to your keyword phrase.

I've created a nifty tool that does all of the hard work for you in
just a click... type a keyword or phrase below:


Enter a keyword or phrase:        
Powered by Google.com 

As you can see, the way I programmed the above script to tap into
Google actually delivers the keywords in phrases directly in Google's
results!

But you might click on each individual listing to visit their site.
Then open the Web page's source code and look for the keyword META tag
section to see all of the meta keywords.

This is one of my favorite ways to find keywords... it's a goldmine of
keyword suggestions to "inspire" you.

I say "inspire", but just so you know -- keywords and phrases are
generally not copyright protected (unless they're trademarked). "

That would be to peak from a google search. But they also have posted
a few other you may want to try out. Now it seems to only search in
meta tag fields and not in the java tags such as bookmarking usually
uses.
