Perhaps you should try some spelling variations:
"spatial inequality" » "social inequality"
"racial inequality" » "social inequality", "regional inequality", "global inequality"
"social reality" » "social inequality"
"social equity" » "social inequality"

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: (((((("racial inequality") OR ("spatial inequality"))) OR ("social reality"))) OR ("social equity")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"racial inequality\") OR (\"spatial inequality\"))) or (\"social reality\"))) or (\"social equity\"))".
• Removing quotes may allow a broader search: (((((( racial inequality ) OR ( spatial inequality ))) or ( social reality ))) or ( social equity )).
• Adding a wildcard symbol may retrieve word variants: (((((("racial inequality") OR ("spatial inequality"))) or ("social reality"))) or ("social equity"))*.
