But Google indexes the whole web. I want a search that works just over the articles I've read.

"What was that article I read a few months back that talked about why you should be able to explain why a fence exists before tearing it down?". It works be perfect for the discussion I'm having with my team right now, but I can't remember the name of the stupid law or where I came across it .

Google is useless in these situations. I need an index contained by my prior search history. Had anyone built this yet?
