• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((chieu xanh) OR (chieu sang)) - manh khung cua ((nhung tuong) OR (nhung huong)) dan van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu sang)) - manh khung cua ((nhung tuong) or (nhung huong)) dan van ban".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu sang)) - manh khung cua ((nhung tuong) or (nhung huong)) dan van ban*.
