Don't miss that in Relativity you can run a dtSearch which will exclude documents where a search term appears in a longer phrase. Use the NOT operator together with the proximity operator set to zero.

Simply follow the search term with: NOT w/0

. . . and then enter the phrase or phrases you don't want to appear in the search results.

This search will turn up documents where 'confidential' appears in the body of an email or document, but not in a disclaimer frequently found at the bottom of an email.
