• Performing a fuzzy search may retrieve terms with similar spellings: su sach v nang ma hoi. hieu ((ve cam) or (va cam)) luc ((va thanh) OR (va tinh)) cua cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang ma hoi. hieu ((ve cam) OR (va cam)) luc ((va thanh) OR (va tinh)) cua cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang ma hoi. hieu ((ve cam) or (va cam)) luc ((va thanh) OR (va tinh)) cua cua triet".
