Perhaps you should try some spelling variations:
dong yang » dong hoang, yang yang, dan yang
wang yang » wang yan, wang liang, wang yanling
gene yang » gene bank
yang min » yang mind, yang jin, tang min
min dang » yimin dang, mein dank, bin dann
ye a » yet a, me a, y a
e a » et a
hai » hadi, haji, hari

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dong yang) OR (wang yang)) ((ye a) or (e a)) gene yang min dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong yang) OR (wang yang)) ((ye a) OR (e a)) gene yang min dang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong yang) OR (wang yang)) ((ye a) or (e a)) gene yang min dang hai ;*".
