If you struggle to get any of your indexing working, let me know and I can Google it, whilst you grep through your stale Stack Overflow archive.

Your reply seems pointless, yes I could download an entire copy of Wikipedia, compress it and index it - why would I want to? Are you going to do this on every machine you own? What about the updates Wikipedia receives every minute?

You should start a company though to focus on this, maybe you could call it Encarta or something?
