• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu sang) OR (tiem nang)) - hanh trang cua tong ((huong van) OR (duong van)) than tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu sang) OR (tiem nang)) - hanh trang cua tong ((huong van) or (duong van)) than tap".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu sang) OR (tiem nang)) - hanh trang cua tong ((huong van) or (duong van)) than tap*.
