Perhaps you should try some spelling variations:
among masters » among partners, among farmers, among actors
patients 1.8 » patients 10.1, patients 10.5, patients 10.6
de patients » des patients, do patients, de pacientes
1.8 among » 1.5 among, 19 among, 1 among
yan yang » yang yang, yao yang, yan wang
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang
aan de » van de, jan de

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