• Performing a fuzzy search may retrieve terms with similar spellings: vu hai ky ((((tang van) OR (hoang van))) or (dang van)) hoi. hieu ve cac xuc va dau de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu hai ky ((((tang van) OR (hoang van))) OR (dang van)) hoi. hieu ve cac xuc va dau de cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu hai ky ((((tang van) OR (hoang van))) or (dang van)) hoi. hieu ve cac xuc va dau de cua tre*".
