• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (((chieu xanh) OR (hieu manh)))) - thanh trung cua thuong cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (((chieu xanh) OR (hieu manh)))) - thanh trung cua thuong cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (((chieu xanh) OR (hieu manh)))) - thanh trung cua thuong cong dan than cau*.
