• If you are trying to use Boolean operators, they must be ALL CAPS: ((ve cac) OR (tu san)) ky ((nang ma) OR (nang cao)) hoi. hieu va pham duy va han thai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ve cac) or (tu san)) ky ((nang ma) OR (nang cao)) hoi. hieu va pham duy va han thai cua tre*".
