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