Perhaps you should try some spelling variations:
development center » development centre, development chapter, development context
development inter » development index, development intra, development internal
development inthe » development intra, development invoke, development incces
working papers » working paper
center working » centred working, century working, inter 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 inter) OR (development inthe)) working papers ) OR ( oriented development center working papers )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( oecd ((development inter) OR (development inthe)) working papers ) or ( oriented development center working papers ))".
• Adding a wildcard symbol may retrieve word variants: (( oecd ((development inter) OR (development inthe)) working papers ) or ( oriented development center working papers ))*.
