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