• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sina) OR (dong sin)) yaa hua chen yang ((amin hong) OR (min hong)) ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sina) or (dong sin)) yaa hua chen yang ((amin hong) OR (min hong)) ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((dong sina) or (dong sin)) yaa hua chen yang ((amin hong) OR (min hong)) ghi ;*.
