Perhaps you should try some spelling variations:
cost patients » cost patient, cleft patients, care patients
patients risk » patient risk, patients links, patients si
risk along » risk among, ask along
kann oder » kann der, kant oder, kann aber
along way » long way, along a, wrong way
lang yan » wang yan, wang yang, zhang yan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((kann oder) OR (kann die)) cost patients risk along way ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((kann oder) or (kann die)) cost patients risk along way ;*.
