Perhaps you should try some spelling variations:
oecd development » child development, based development, oriented development
context working » contexts working, content working, contents working
center working » centred working, century working, better working
working papers » working paper
inter working » internet working, inter networking, interface working

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: (( oecd development ((center working) OR (inter working)) papers ) OR ( oecd development context working papers )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( oecd development ((center working) OR (inter working)) papers ) or ( oecd development context working papers ))".
• Adding a wildcard symbol may retrieve word variants: (( oecd development ((center working) OR (inter working)) papers ) or ( oecd development context working papers ))*.
