• Performing a fuzzy search may retrieve terms with similar spellings: su sach ly ((mang xa) or (nang ma)) hoi. thien van lam ((duoc van) OR (duc van)) anh va cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly ((mang xa) OR (nang ma)) hoi. thien van lam ((duoc van) OR (duc van)) anh va cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly ((mang xa) or (nang ma)) hoi. thien van lam ((duoc van) OR (duc van)) anh va cua triet*".
