Perhaps you should try some spelling variations:
gender case » gender caste, gender based, gender class
gender das » gender bias, gender data, gender a
als last » als gast, a last, his last
li last » i last, die last, his last
wang » wing, wan, lang
yanling » yanlong, yanline, yanwing
ling » long, line, wing

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 yanling ling ((li last) OR (als last)) third ((gender das) OR (gender case)) bin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ling ((li last) or (als last)) third ((gender das) OR (gender case)) bin ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ling ((li last) or (als last)) third ((gender das) OR (gender case)) bin ;*.
