• If you are trying to use Boolean operators, they must be ALL CAPS: te ban ((((ky trong) OR (ke trong))) OR (ky nang)) mai hoi. hieu ve chat luc va thanh tri cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ban ((((ky trong) OR (ke trong))) or (ky nang)) mai hoi. hieu ve chat luc va thanh tri cua tre*".
