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