• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh trung cua khong ((((thong thanh) OR (truong thanh))) OR (thong than)) san tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh trung cua khong ((((thong thanh) OR (truong thanh))) or (thong than)) san tap".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh trung cua khong ((((thong thanh) OR (truong thanh))) or (thong than)) san tap*.
