Perhaps you should try some spelling variations:
"feudal property prediction" » "feudal property protection", "real property prediction", "thermal property prediction"
"feudal property reduction" » "feudal poverty reduction", "feudal properties reduction", "feudal property predictions", "real property reduction", "thermal property reduction"
"rural poverty protection" » "rural property protection", "rural poverty projections", "rural poverty production"

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: (((("feudal property reduction") OR ("feudal property prediction"))) OR ("rural poverty protection")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"feudal property reduction\") OR (\"feudal property prediction\"))) or (\"rural poverty protection\"))".
• Removing quotes may allow a broader search: (((( feudal property reduction ) OR ( feudal property prediction ))) or ( rural poverty protection )).
• Adding a wildcard symbol may retrieve word variants: (((("feudal property reduction") OR ("feudal property prediction"))) or ("rural poverty protection"))*.
