Perhaps you should try some spelling variations:
things during » things using, things sharing, thing hiring
last things » last thing, first things, smart things
ying yang » yang yang, yin yang, ying chang
dong yang » dong hoang, wang yang, yang yang
data box » data big
a last » _ last, a las
book » books, ebook

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 ((ying yang) OR (dong yang)) a last things during ((data box) OR (data book)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ying yang) or (dong yang)) a last things during ((data box) OR (data book)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ying yang) or (dong yang)) a last things during ((data box) OR (data book)) ;*.
