• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chau tinh)) - hanh tranh cua ((nhung cong) OR (hang cong)) san toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chau tinh)) - hanh tranh cua ((nhung cong) OR (hang cong)) san toan ban*.
