• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang ma hoa. hieu ((ve cam) OR (va cam)) dua ban ((thanh hai) OR (thanh hoa)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang ma hoa. hieu ((ve cam) or (va cam)) dua ban ((thanh hai) OR (thanh hoa)) cua tre*".
