Question of Range search
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!

You need to implement a query filter plugin. See, for example:
http://svn.apache.org/viewcvs.cgi/lucene/nutch/trunk/src/plugin/query-more/src/java/org/apache/nutch/searcher/more/DateQueryFilter.java?rev=179640&view=markup
