• The words AND, OR and NOT may confuse the search; try adding quotes: "lang planning can china ((fan ying) or (ran ying)) lin ((zhong zhi) OR (hong ghi)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang planning can china ((fan ying) or (ran ying)) lin ((zhong zhi) OR (hong ghi)) ;*.
