Perhaps, but here is the url generated when I check only the test DB 
selection:

http://localhost/cgi-bin/omega?P=yifan+ram&DB=tst.db&DEFAULTOP=or&DB=tst.db%2Fdefault&FMT=query&xP=yifan.ram.&xDB=tst.db%2Fdefault&xFILTERS=--O
Something in there is doing something strange.  There are two DB 
parameters and they both list both DBs.  It's obvious from the output it 
is searching the default DB anyway from the data that was found. 

Thanks,
Jim.
