• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu xanh) OR (hieu manh)) - hanh ((trung cua) OR (dung luan)) nhung hong van tuan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) OR (hieu manh)) - hanh ((trung cua) or (dung luan)) nhung hong van tuan cu~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) OR (hieu manh)) - hanh ((trung cua) or (dung luan)) nhung hong van tuan cu*.
