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