All,
Just to amplify Chris' posts....
One of the new features in ProDiscover 6 is the ability index live disks and images. This feature will support the indexing of PDF, XML (including .DOCX) and other file types. We'll be working on internal viewers within ProDiscover post 6.0 release. So, in addition to the pre-processed work around posted above, the index base search will return search sets not currently supported in our RAW search.
