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