title: ServiceNow Encoded Query validation
body: <p>I intend to let users specify <a href="http://wiki.servicenow.com/index.php?title=Embedded%3aEncoded_Query_Strings" rel="nofollow" title="ServiceNow wiki - Encoded query strings">encoded query</a> in ServiceNow SOAP requests.</p>
  
  <p>The problem is that if user specifies invalid query string (e.g. "?#@" or "sometext"), ServiceNow do not return any exception, but every row or no rows at all.</p>
  
  <p>Is there a way to check validity of encoded query via webservice?</p>
