No, not Google. We're in a completely different market. We index
almost as many documents a google. During a search/query, Google is
not required to return all documents -- we do. Google only indexes
10,000 terms/tokens in a document, we have no limit. If the document
is greater than 101K (after conversion), Google will not index; we
have no limit. This info is from friends inside of Google.
Compliance market is completely different.

Our systems are mirrored (two servers contain the same data).
However, it would take too long to do this procedure on 2000 servers,
not to mention the fact that this would be an operational nightmare.

Agree. I had to mention Fedora because it's a "development" release
so ideas from here could be used.
