	<BR>Note: if a search takes particularly long to run (e.g. more than 10 minutes) 
	 your browser or webserver session may time out and instead of getting the search
	 result, you may get the warning 'Document contained no data'. Possible solutions:
	 change the setting of the WebServer and/or the Browser, to have them allow more
	 time before a session/request is timed out. Or: change the search criteria to be
	 more selective. Or add the additional where clause 1=2 and copy and paste the query
	 (minus the line AND 1=2) into SQL*Plus or another environment.
