• If you are trying to use Boolean operators, they must be ALL CAPS: tu xach ((tay lang) OR (tai lang)) ma hoi. hieu qua ca duc va kinh ((di cau) OR (da cau)) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu xach ((tay lang) OR (tai lang)) ma hoi. hieu qua ca duc va kinh ((di cau) or (da cau)) tren".
• Adding a wildcard symbol may retrieve word variants: tu xach ((tay lang) OR (tai lang)) ma hoi. hieu qua ca duc va kinh ((di cau) or (da cau)) tren*.
