• Performing a fuzzy search may retrieve terms with similar spellings: ((toc cach) OR (hoc cach)) tu nano cho hoc. thien van hoc ((vuc van) or (luc van)) danh de cua chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc cach) OR (hoc cach)) tu nano cho hoc. thien van hoc ((vuc van) OR (luc van)) danh de cua chu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc cach) OR (hoc cach)) tu nano cho hoc. thien van hoc ((vuc van) or (luc van)) danh de cua chu*".
