• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thi hang cho hoc. ((lieu va) OR (lieu van)) cac vuc van hanh vai ((cua cau) OR (cua cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thi hang cho hoc. ((lieu va) or (lieu van)) cac vuc van hanh vai ((cua cau) OR (cua cac))*".
