• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky tang mai hoi. hieu ve cham xuc ((va xanh) OR (((va hanh) OR (van hanh)))) dai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky tang mai hoi. hieu ve cham xuc ((va xanh) or (((va hanh) OR (van hanh)))) dai cuu tre*".
