• If you are trying to use Boolean operators, they must be ALL CAPS: o chau tinh - ((hanh trang) OR (canh tranh)) cua ((nhung cong) OR (hang cong)) ban than cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o chau tinh - ((hanh trang) or (canh tranh)) cua ((nhung cong) OR (hang cong)) ban than cao".
