Perhaps you should try some spelling variations:
based mapping » based cropping, based machine
mapping using » mapping business
line based » fire based, rice based
ying yang » yang yang, yin yang, ying chang
yang line » yang lin, yang liang, yang jie
dong sind » dong sin, dong bin, dong ping
ran ying » fan ying, tan ying, jin ying
dort hin » dort bin, dort ii, dort von
art von » ort von, kurt von

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: ran ying yang line based mapping using ((((art von) OR (dort hin))) OR (dong sind)) ;~.
• Adding a wildcard symbol may retrieve word variants: ran ying yang line based mapping using ((((art von) or (dort hin))) or (dong sind)) ;*.
