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