[rules-users] "distinct" operator in a query

Hello guys, I make a very simple question, especially for a curiosity. I have this query: query "QuerySelected" $result: Person( identifierCode == "ABCDEF12H45S100A" ) $y: YearData( id == $result.identifierCode ) exists Vehicle( ) from $y.vehicles end With this query i get two equal person results because there are two annual that matches with condition. There is a simple way in drools to apply "distinct" operator or avoid this behaviour.
