Perhaps you should try some spelling variations:
comparative macroeconomic » comparative economic, comprehensive macroeconomic, alternative macroeconomic
comparative economics » comparative economic, comparative genomics, comparative genomic
world daria » world darcia, world maria, world darwin

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: (( the world daria ((comparative macroeconomic) OR (comparative economics)) studies ) OR ( the world data ((comparative macroeconomic) OR (comparative economics)) studies )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( the world daria ((comparative macroeconomic) OR (comparative economics)) studies ) or ( the world data ((comparative macroeconomic) OR (comparative economics)) studies ))".
• Adding a wildcard symbol may retrieve word variants: (( the world daria ((comparative macroeconomic) OR (comparative economics)) studies ) or ( the world data ((comparative macroeconomic) OR (comparative economics)) studies ))*.
