• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang ma hoa. ((hieu ve) OR (hieu va)) cham xuc ban ((thanh hai) OR (thanh phan)) cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang ma hoa. ((hieu ve) OR (hieu va)) cham xuc ban ((thanh hai) or (thanh phan)) cuc tre".
