Google Desktop Web Search for OS X

Does anyone know of anything that give you the equivalent feature that Google Desktop gives you that allows for you to search the text in web pages that you have previously visited in OS X?  For example in Google Desktop if i put in “North Korean Peninsula” into the search box it would also search inside web pages that I had previously looked at to find “North Korean Peninsula” in the text of the page.  I just switched to a new Powerbook 12” and I’m looking for a program that will do this if there is such a thing that exists.  I really liked that feature of Google Desktop.  Sorry if this is badly worded, but it is a little hard to explain.  Anyway kThanksBye.

Perhaps you can get away by searching directly your browser cache files. I don't know how would you do this in a Mac, but I believe you should be able to. Use a command line. See if there's a Midnight Commander port for OS X, there probably is. It's not FAR, but it's good enough for that.
