• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ((ky sang) OR (ky dang)) lap hoi. tieu su ((chan xu) OR (chao xu)) ban thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky sang) or (ky dang)) lap hoi. tieu su ((chan xu) OR (chao xu)) ban thanh vi cua te".
