• The words AND, OR and NOT may confuse the search; try adding quotes: "wai yan ((yang fan) or (yang yang)) ((de patients) OR (des patients)) 1.8 among partners ;~".
• Adding a wildcard symbol may retrieve word variants: wai yan ((yang fan) or (yang yang)) ((de patients) OR (des patients)) 1.8 among partners ;*.
