Perhaps you should try some spelling variations:
yang uganda » yang anda, bank uganda, lanka uganda
uganda how » agenda how, uganda joy, uganda who
dong yang » dong hoang, wang yang, yang yang
than daun » than bau, than daem, than data
can data » can tata, dan data, fan data
how hai » how has, how ai, how hci
dean » dewan, jean, den

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: dong yang dean ((than daun) OR (can data)) yang uganda how hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang dean ((than daun) or (can data)) yang uganda how hai ;*.
