among actors » among doctors, among acholi, among donors
de patients » des patients, do patients, de pacientes
wang yang » wang yan, wang liang, wang yanling
dan yang » daun yang, tan yang, yang yang
jan de » van de, aan 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: wang ((dan yang) OR (wang yang)) jan de patients 1.8 ((among farmers) OR (among actors)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((dan yang) OR (wang yang)) jan de patients 1.8 ((among farmers) or (among actors)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((dan yang) OR (wang yang)) jan de patients 1.8 ((among farmers) or (among actors)) ;*.
