ars_LoadQualifier(ctrl, schema, qualstring, displayTag)The qualifier string may contain field IDs or field labels. Using field labels, however, does reportedly not always work reliable, so it is strongly recommended to use field IDs.
   
      When mapping field labels, the server will refer to the view specified
      in displayTag. If no view is specified, the server will use the
      default admin view. It is NOT possible to use database names (returned as "fieldName"
      by ars_GetField) in a qualifier string.

      Example:
      ($q = ars_LoadQualifier($c, "User", "'101' = \"jmurphy\"")) ||
	    die $ars_errstr;
      
	or, to specify a particular view:
      
      ($q = ars_LoadQualifier($c, "User", "'User name' = \"jmurphy\"", 
				"PC-640")) ||
	    die $ars_errstr;
