Customer Name Search in Search Form with leading % sign

HI,

How can I search Customer Name in Search Form with leading % sign while the form displays following Error Message:

"Please fill in search criteria values in at least one of the following fields: Customer, Registry ID, Account Number, Account Description, Tax Registration Number, Taxpayer ID, D-U-N-S Number, Contact First Name, Contact Last Name, Contact Phone Number, Address Line 1. Note that the search criteria values should not begin with a "%" or "_" for at least one of the listed fields."

Can anyone guide me?

Thanks in Advance
