• If you are trying to use Boolean operators, they must be ALL CAPS: tu xach tay lang ma hoi. hieu qua cao duc va dinh ((diem cau) OR (((da cau) OR (dat cau)))) tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu xach tay lang ma hoi. hieu qua cao duc va dinh ((diem cau) or (((da cau) OR (dat cau)))) tren".
