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

[braveheart85]

First thing I'm sorry for stealing your time.
What you say is true in this case, but what about case which i would add a
constraint to Vehicle:

query "QuerySelected" 
        $result: Person( identifierCode == "ABCDEF12H45S100A" ) 
        $y: YearData( id ==  $result.identifierCode ) 
        exists Vehicle( model == "foobar" ) from $y.vehicles 
end 

Then again maybe my question is stupid.
