• If you are trying to use Boolean operators, they must be ALL CAPS: lang ((yan ka) OR (yang ka)) hua rents yang ((wu zhong) OR (2 zhong)) zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan ka) or (yang ka)) hua rents yang ((wu zhong) OR (2 zhong)) zhi ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan ka) or (yang ka)) hua rents yang ((wu zhong) OR (2 zhong)) zhi ;*.
