Perhaps you should try some spelling variations:
among masters » among partners, among farmers, among letters
patients 1.8 » patients 10.1, patients 10.5, patients 10.6
among actors » among doctors, among acholi, among donors
de patients » des patients, do patients, de pacientes
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang
fan de » van de, aan 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 ((tan yang) OR (dan yang)) fan de patients 1.8 ((among masters) OR (among actors)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((tan yang) or (dan yang)) fan de patients 1.8 ((among masters) OR (among actors)) ;~".
• Adding a wildcard symbol may retrieve word variants: wai ((tan yang) or (dan yang)) fan de patients 1.8 ((among masters) OR (among actors)) ;*.
