• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh trung cap ((tuong dong) OR (trong dong)) ((dan than) OR (dan chan)) cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh trung cap ((tuong dong) OR (trong dong)) ((dan than) or (dan chan)) cap*".
