• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (bo sach)) ly sang ma hoa. dieu hien dai thu vat danh ((vi cua) OR (di cua)) vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (bo sach)) ly sang ma hoa. dieu hien dai thu vat danh ((vi cua) OR (di cua)) vat~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (bo sach)) ly sang ma hoa. dieu hien dai thu vat danh ((vi cua) OR (di cua)) vat*.
