Perhaps you should try some spelling variations:
germany gender » german gender, germany under, germany der
hong gang » gong gang, hong wang, hong kong
yang jui » yang judy, yang xi, yang yi
nan yan » nan ya, wang yan, qian yan
nr 2012 » drk 2012
amp 2 » amp d, amp _, amp e
amp m » amp d

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: ((((nan yan) OR (yang jui))) OR (yang di))nr 2012 germany gender ((amp 2) OR (amp m)) hong gang ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((nan yan) or (yang jui))) or (yang di))nr 2012 germany gender ((amp 2) OR (amp m)) hong gang ;~".
• Adding a wildcard symbol may retrieve word variants: ((((nan yan) or (yang jui))) or (yang di))nr 2012 germany gender ((amp 2) OR (amp m)) hong gang ;*.
