Perhaps you should try some spelling variations:
states during » rates during, states making, strategies during
states using » rates using, estimates using, studies using
take small » take all, takes all, wave small
land take » land taxes, land tax
yin fang » yin hang, yin yang, chin fang
yu yang » du yang, yi yang, yu fang

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: ((yin fang) OR (yu yang)) land take small ((states using) OR (states during)) dem bei ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yin fang) or (yu yang)) land take small ((states using) OR (states during)) dem bei ;~".
• Adding a wildcard symbol may retrieve word variants: ((yin fang) or (yu yang)) land take small ((states using) OR (states during)) dem bei ;*.
