Date Property to Search in PDM

I want to create a Custom Property for Date to be used in searching for files checked in on a certain date in the Vault.

I can go to the Properties tab in the VaultAdmin to create a custom property called Date - BUT what do I map to?

I tried SW-ShortDate and different variations, thereof; i.e. \$PRP-SW-ShortDate, etc. but so far no luck.

Any ideas?

Thanks
