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