• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu dan) OR (cu dan)) ky ((lang xa) OR (nang x)) hoi. hieu ve cac tuc va hanh kem ca tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu dan) OR (cu dan)) ky ((lang xa) or (nang x)) hoi. hieu ve cac tuc va hanh kem ca tren".
