are all search engine indexes created alike?
You might think that if you set up traps on one search engine you don't need to bother with
them on others. “They all index the internet,” you might say. “isn't one just like the other?”
deinitely not! only so much overlap exists in the indexes of the various search engines. if you
only monitor one, you're deinitely going to miss information from the others. This might lead
you to another question: “if i monitor all the major search engines, i'll be monitoring all the new
pages added to the internet, right?” afraid not. Though you'll be covering a lot more of the
internet than you would otherwise, all the search engines put together do not index more than
a part of the internet's Web pages.
Bottom Line: monitor several search engines and you'll get all you can, but you still won't be
getting everything.

text search engine now.
