• Performing a fuzzy search may retrieve terms with similar spellings: so sac ky danh xay hoi. ((thien van) or (hieu va)) bac xuc van ((hanh han) OR (hanh san)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky danh xay hoi. ((thien van) OR (hieu va)) bac xuc van ((hanh han) OR (hanh san)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky danh xay hoi. ((thien van) or (hieu va)) bac xuc van ((hanh han) OR (hanh san)) cua tre*".
