Tue, Peter, but those webpages Google searches are webpages Google has cached. That's why I use at least two different browsers for a serious websearch -- usually, but not always, Google, and a metasearch engine such as Metacrawler.

The importance of using cached for Google (and other search engines) is that they have already been indexed. Naturally, this speeds up your data retrieval enormously.

I'm not aware of ANY search engine that can search the ENTIRE World Wide Web in any acceptable response time without using previously cached and indexed pages -- "on the fly" so to speak.

Put another way, every web search engine is simply the catalog to a library of a huge number of indexed web pages. You'll get to the current edition of the "book" as long as the "book" is still there. If the "book" has been discarded by the "library" it might still be in the catalog, but if you want to read it you'll find it missing (get a 404 or 405 error, most likely).
