Perhaps you should try some spelling variations:
securing food » security food, measuring food, securing land
sharing food » sharing hold, sharing covid, sharing forms
ying chang » jin chang, yi chang, yin hang
chang yun » chong yun, chang hsun, chae yun
da loss » a loss, data loss, gdp loss
kong » long, hong, pong

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: ying chang yun da loss ((sharing food) OR (securing food)) kong (sar OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ying chang yun da loss ((sharing food) OR (securing food)) kong (sar or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: ying chang yun da loss ((sharing food) OR (securing food)) kong (sar or saur) ;*.
