• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu sach)) - hanh tang cua dung ((cong manh) OR (cong thanh)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu sach)) - hanh tang cua dung ((cong manh) OR (cong thanh)) toan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu sach)) - hanh tang cua dung ((cong manh) OR (cong thanh)) toan cao*.
