• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((hieu manh) OR (chieu xanh)) - ((dang thuong) OR (dung thuong)) qua thong duong dan van ban~".
• Adding a wildcard symbol may retrieve word variants: toc ((hieu manh) OR (chieu xanh)) - ((dang thuong) OR (dung thuong)) qua thong duong dan van ban*.
