• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach kho tang van hoa. lieu ((va cam) OR (va cao)) xuc van doanh ((vang cua) OR (mang cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach kho tang van hoa. lieu ((va cam) OR (va cao)) xuc van doanh ((vang cua) or (mang cua)) te~".
• Adding a wildcard symbol may retrieve word variants: tu sach kho tang van hoa. lieu ((va cam) OR (va cao)) xuc van doanh ((vang cua) or (mang cua)) te*.
