• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty dang van hoi. hieu ((va cam) OR (va cac)) duc ((va thanh) or (gia thanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty dang van hoi. hieu ((va cam) OR (va cac)) duc ((va thanh) OR (gia thanh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty dang van hoi. hieu ((va cam) OR (va cac)) duc ((va thanh) or (gia thanh)) vi cua triet*".
