• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang van hoi. hieu ((va cam) or (va cao)) tuc va dung ((tai cua) OR (tai cuc)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang van hoi. hieu ((va cam) OR (va cao)) tuc va dung ((tai cua) OR (tai cuc)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang van hoi. hieu ((va cam) or (va cao)) tuc va dung ((tai cua) OR (tai cuc)) tre".
