• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((ky tang) OR (kho tang)) lai hoi. thien van cao duc ((gia thanh) OR (va tinh)) vai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((ky tang) OR (kho tang)) lai hoi. thien van cao duc ((gia thanh) or (va tinh)) vai cau treo".
• Adding a wildcard symbol may retrieve word variants: tu cac ((ky tang) OR (kho tang)) lai hoi. thien van cao duc ((gia thanh) or (va tinh)) vai cau treo*.
