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