• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu xanh) OR (chieu sach)) - hanh nang luong khong duong manh ((toan tai) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - hanh nang luong khong duong manh ((toan tai) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - hanh nang luong khong duong manh ((toan tai) or (toan cao))".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - hanh nang luong khong duong manh ((toan tai) or (toan cao))*.
