• If you are trying to use Boolean operators, they must be ALL CAPS: dong hoang ka ((tan ran) OR (tan tan)) ying jin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hoang ka ((tan ran) OR (tan tan)) ying jin ((hong hai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong hoang ka ((tan ran) OR (tan tan)) ying jin ((hong hai) or (shang hai)) ;*.
