We have found today a great and free Tool to check or see what iFilters are installed on a Server or other Windows-System.
We have used today this great Tool to verify wy specified Files with different File Extension not returned in DMX Search Results.
The problem is not by DMX!!!! But by Lucene what use for each File-Extension a iFilter on the Server, is the needed iFilter not on the Server-System so is the File not indexed from Lucene and not displayed in DMX-Search Results.
iFilter Explorer from citeknet is available as 32bit and 64bit Version here (http://wwwciteknet.com/)
