• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((you xian) OR (you liang)) die risiko sharing oil ((hong ng) OR (long arm)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((you xian) OR (you liang)) die risiko sharing oil ((hong ng) or (long arm)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((you xian) OR (you liang)) die risiko sharing oil ((hong ng) or (long arm)) ;*.
