[rules-dev] Parameters in DROOLS Queries?

I would like to create a DROOLS Query that allows parameters to be passed in from the Java side. This would allow me to easily filter the query results without changing the query itself. Other rule engines (e.g., JESS) can parameterize queries and this is a very powerful feature. But can DROOLS provide parameters to its queries? Or is there some design "pattern" or rule-of-thumb I should use to filter query results? Thanks, Phil
