Hmmm... I never use range queries, but that "????" part looks suspicious.  Sorry, can't help
more now, maybe somebody else will have the answer for you.  Sit tight.

Thanks for your reply Otis,

wquery.toString()  returns  westbc:[* TO ????]
query.toString() returns westbc:[* TO ????]

If I compare these two strings for equality like
wquery.toString().equals(query.toString()) I get true. I also got bytes of
those strings and compared them bytewise - they are equal this way too.

Ideas are welcome.

Leonid
