• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky ((lang van) OR (hoang van)) hoi. lieu va cao xuc van hanh ((di cua) or (dai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((lang van) OR (hoang van)) hoi. lieu va cao xuc van hanh ((di cua) OR (dai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((lang van) OR (hoang van)) hoi. lieu va cao xuc van hanh ((di cua) or (dai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu san ky ((lang van) OR (hoang van)) hoi. lieu va cao xuc van hanh ((di cua) or (dai cua)) triet*.
