• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky danh sai hoi. ((hieu vu) OR (hieu va)) cham xuc va ((hanh vai) OR (hanh va)) ca tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky danh sai hoi. ((hieu vu) OR (hieu va)) cham xuc va ((hanh vai) or (hanh va)) ca tren*".
