Perhaps you should try some spelling variations:
"social equality" » "social inequality", "social reality", "social morality"
"racial equality" » "racial inequality", "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: (((("social equality") OR ("racial equality"))) OR ("social equity")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"social equality\") OR (\"racial equality\"))) or (\"social equity\"))".
• Removing quotes may allow a broader search: (((( social equality ) OR ( racial equality ))) or ( social equity )).
• Adding a wildcard symbol may retrieve word variants: (((("social equality") OR ("racial equality"))) or ("social equity"))*.
