+// Query: (abstract) a parsed, 'executable' digger database query
+//        a query tree is formed by leaf objects (ExactWordQuery) and
+//        node objects (OperatorQuery) derived from this class.
+//        Query execution results are returned as ResultList objects.
+//        Query evaluation is cached. Cache policy is delegated to the
+//        QueryCache class family.
