• If you are trying to use Boolean operators, they must be ALL CAPS: lang nan yan zi zhen ((zhang xin) OR (zhang ming)) ((song sein) OR (song jin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang nan yan zi zhen ((zhang xin) or (zhang ming)) ((song sein) OR (song jin)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang nan yan zi zhen ((zhang xin) or (zhang ming)) ((song sein) OR (song jin)) ;*.
