• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty nang chon hoc. ((hieu ve) OR (hieu va)) cac ((luc van) OR (luu van)) hanh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty nang chon hoc. ((hieu ve) or (hieu va)) cac ((luc van) OR (luu van)) hanh vi cua cau*".
