• If you are trying to use Boolean operators, they must be ALL CAPS: phu ((nhieu tang) OR (nhiet nang)) - hanh trung cua dung cong dan ((nhan tai) OR (hang tai))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "phu ((nhieu tang) OR (nhiet nang)) - hanh trung cua dung cong dan ((nhan tai) or (hang tai))*".
