Perhaps you should try some spelling variations:
dong hoang » hong hong
hoang dean » yang dean
than daun » than bau, than daem, than data
can data » can tata, dan data, fan data
yang jin » yang jie, yang jun, ying jin
jin how » john how
how hai » how has, how ai, how hci

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hoang dean ((than daun) OR (can data)) yang jin how hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong hoang dean ((than daun) OR (can data)) yang jin how hai ;*.
