Different users are unable to search records

Different users are unable to search records

The following call is made: 

crmAcct = zoho.crm.v1.searchRecords("Accounts","(Account Name|=|" + acct + ")");

This call works successfully when the call is invoked by the Admin.  However when a non admin user invokes this call I get the following:

Invalid collection string Line:(10)

Any help would be greatly appreciated.
