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