• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sai) OR (vu san)) kho tang ((van hoi) or (van hoa)). hieu ve cam xuc va dan dieu cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sai) OR (vu san)) kho tang ((van hoi) OR (van hoa)). hieu ve cam xuc va dan dieu cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sai) OR (vu san)) kho tang ((van hoi) or (van hoa)). hieu ve cam xuc va dan dieu cua tre*".
