• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chuc danh) OR (thuc hanh))) OR (chieu xanh)) - hanh tang cua nhung cong tan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chuc danh) OR (thuc hanh))) or (chieu xanh)) - hanh tang cua nhung cong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chuc danh) OR (thuc hanh))) or (chieu xanh)) - hanh tang cua nhung cong tan toan ban*.
