• Performing a fuzzy search may retrieve terms with similar spellings: theo ((((tieu tinh) OR (trieu tinh))) or (tieu trinh)) - lanh sang va dung cong dan ca cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((tieu tinh) OR (trieu tinh))) OR (tieu trinh)) - lanh sang va dung cong dan ca cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((tieu tinh) OR (trieu tinh))) or (tieu trinh)) - lanh sang va dung cong dan ca cau".
• Adding a wildcard symbol may retrieve word variants: theo ((((tieu tinh) OR (trieu tinh))) or (tieu trinh)) - lanh sang va dung cong dan ca cau*.
