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