• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((thanh truong) OR (thanh tung)) quan dung ((cong dan) OR (cong san)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((thanh truong) OR (thanh tung)) quan dung ((cong dan) or (cong san)) toan cau*".
