• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((mang cua) OR (((dang xay) OR (dang van)))) hoi. thi nang cac duc va nhanh hai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((mang cua) or (((dang xay) OR (dang van)))) hoi. thi nang cac duc va nhanh hai cua viet*".
