• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky mang day hoa. hieu ((ve cam) OR (ve cham)) ((xuc va) OR (tuc va)) dinh viet cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky mang day hoa. hieu ((ve cam) or (ve cham)) ((xuc va) OR (tuc va)) dinh viet cua te*".
