Question of Range search

[Game Now]

Hi All,

I wanna Nutch help me do a range search, such as price:{1000 TO 2000}
or date[20050101 TO 20051111].

But org.apache.nutch.searcher.Query#parse() method parse them to
"price 1000 2000" and "date 20050101 20051111" when i pass them to the
method.

Anybody can help me complete a range search in Nutch?

Thank you!
