Perhaps you should try some spelling variations:
based cropping » mixed cropping, based costing
cropping using » mapping using, cracking using, cropping looking
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
fan ying » fan xing, ran ying, tan ying
dort von » ort von, hort von, art von
dort bin » dort hin, dong bin, dort ii

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: fan ying yang line based cropping using ((((dort von) OR (dort bin))) OR (dong sind)) ;~.
• Adding a wildcard symbol may retrieve word variants: fan ying yang line based cropping using ((((dort von) or (dort bin))) or (dong sind)) ;*.
