Perhaps you should try some spelling variations:
things during » things using, things sharing, thing hiring
huang ting » huang jing, huang ying, huang bin
net things » get things, new things, set things
dan huang » d huang, dan yang, dr huang
bed net » bed nets
dong di » dong sin
dort ii » dort bin, dort hin

• If you are trying to use Boolean operators, they must be ALL CAPS: dan huang ting bed net things during ((dong di) OR (dort ii)) ;*.
