Problem
When someone runs the search "FullText Fails" emails that have filtered text are returned.
Why
Emails generally aren't large enough to require the extraction of their "filtered text" into a dat file and, therefore, don't have an entry for filtered text in the object streams table.
Work Around
Running "Fulltext Fails", adding the FileType column to the grid, and filtering out "Messages" with the column filters will give you a better result set.
