• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - ((canh tranh) OR (anh nang)) lan dung cong dan toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - ((canh tranh) or (anh nang)) lan dung cong dan toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu sach)) - ((canh tranh) or (anh nang)) lan dung cong dan toan tap*.
