Advanced Indexing and Search for SEV9 on Outlook 2010

Currently using Exchange 2010, SEV9, on Win7 and Outlook2010.  The Search function on Archive Explorer and Outlook2010 plug-in doesn't suit the business needs.  Aside from X1 (http://www.x1.com/), are there any other products which can index items on the vault, allow searching through SEV quicker?
