• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky ((lang van) OR (tang van)) hoi. ((hieu van) OR (thien van)) cac luc va thanh ho cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky ((lang van) or (tang van)) hoi. ((hieu van) OR (thien van)) cac luc va thanh ho cua tre*".
