Parametric Search Appliance
This controls whether this profile is visible to other
Parametric Search Appliances (or even the same one) for use in a meta
search. Any profile that is to be used as a part of a meta search must
have the Visible flag set to Y.
If a profile has Visible set to N and is used as a
back-end for meta search, it will return the error
Profile not Visible.
