• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((lang xa) OR (lang van)) hoi. hieu ((tu cham) or (thi cham)) sac tuan anh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((lang xa) OR (lang van)) hoi. hieu ((tu cham) OR (thi cham)) sac tuan anh vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((lang xa) OR (lang van)) hoi. hieu ((tu cham) or (thi cham)) sac tuan anh vai cua triet*".
