• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. hieu ve cham tuc va danh dau ((((cua tre) OR (dua tren))) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu ve cham tuc va danh dau ((((cua tre) OR (dua tren))) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. hieu ve cham tuc va danh dau ((((cua tre) OR (dua tren))) or (cua triet))".
