• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky tang ((ma hoi) OR (mai hoi)). hieu ve cham xuc ban thanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su xac)) ky tang ((ma hoi) OR (mai hoi)). hieu ve cham xuc ban thanh dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) or (su xac)) ky tang ((ma hoi) OR (mai hoi)). hieu ve cham xuc ban thanh dai cuu tre*.
