• If you are trying to use Boolean operators, they must be ALL CAPS: ((((su cac) OR (tu cac))) OR (su cao)) ky dang ha hoi. hieu ve chat xu van thanh ban cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((su cac) OR (tu cac))) or (su cao)) ky dang ha hoi. hieu ve chat xu van thanh ban cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((((su cac) OR (tu cac))) or (su cao)) ky dang ha hoi. hieu ve chat xu van thanh ban cuu tre*.
