Perhaps you should try some spelling variations:
measuring inequality » measuring quality
garding's inequality » earnings inequality, young's inequality, korn's inequality
garding inequality » earnings inequality, hardy inequality, rising inequality
hardy's inequality » hardy inequality, holder's inequality, harnack inequality
wage » wave

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: wage AND ((measuring inequality) OR (((((garding inequality) OR (garding's inequality))) OR (hardy's inequality)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "wage and ((measuring inequality) or (((((garding inequality) OR (garding's inequality))) or (hardy's inequality))))".
• Adding a wildcard symbol may retrieve word variants: wage and ((measuring inequality) or (((((garding inequality) OR (garding's inequality))) or (hardy's inequality))))*.
