Having left his job more than 15 years ago, is there any chance that he's simply not aware of the actual methods they're using? I know in other fields the ability to do concept searching (via LSI and other techniques), rather than simple text based searching, has been in use for many years. His example/problem of a search for "bomb" bringing up noise (such as an email talking about a QB throwing a 'bomb' pass) should have long ago been solved.
