• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (tu san)) ky ((lang xa) OR (dang xay)) hoi. hieu va cham duc va han thai su tien*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) or (tu san)) ky ((lang xa) OR (dang xay)) hoi. hieu va cham duc va han thai su tien*".
