• Performing a fuzzy search may retrieve terms with similar spellings: su sach tru tang ((ma hoi) OR (xa hoi)). thien van chat xuc ((va hanh) or (ban hanh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tru tang ((ma hoi) OR (xa hoi)). thien van chat xuc ((va hanh) OR (ban hanh)) di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tru tang ((ma hoi) OR (xa hoi)). thien van chat xuc ((va hanh) or (ban hanh)) di cua triet".
