Searching Symantec Enterprise Vault

Hi

We currently use Sherpa's Discovery Attender to run email and file searches across our business. But we're about to move to Symantec Enterprise Vault (EV) for email (Exchange) archiving and the Sherpa product can't search the EV archive so we need to do something different.

Symantec have an add-on (Discovery Accelerator) which will do a job of sorts but from the little I've seen (a) it's expensive (b) result handling isn't great and © documentation/audit trail is poor and requires extensive customisation.

I've looked at the on-line demos for MetaLINCS and Attenex - is anyone out there using anything else (commercial or developed in-house) to search simultaneously through Exchange and EV?

Cheers
