• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu tinh) or (ha tinh)) - nhanh lang luan ban cong dinh ((thanh cac) OR (hanh cac))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu tinh) OR (ha tinh)) - nhanh lang luan ban cong dinh ((thanh cac) OR (hanh cac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (ha tinh)) - nhanh lang luan ban cong dinh ((thanh cac) OR (hanh cac))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (ha tinh)) - nhanh lang luan ban cong dinh ((thanh cac) OR (hanh cac))*.
