• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong ping) OR (dong yang))) OR (dong (sin OR sign))) yala yu chen tan amin zhang zhi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong ping) or (dong yang))) or (dong (sin OR sign))) yala yu chen tan amin zhang zhi ;".
• Adding a wildcard symbol may retrieve word variants: ((((dong ping) or (dong yang))) or (dong (sin OR sign))) yala yu chen tan amin zhang zhi ;*.
