• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky tang ma hoi. hieu ((van cam) OR (van lam)) ((xuc ban) OR (cuc ban)) thanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky tang ma hoi. hieu ((van cam) OR (van lam)) ((xuc ban) or (cuc ban)) thanh dai cuu tre".
