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