Perhaps you should try some spelling variations:
"oecd development control working papers" » "oecd development context working papers", "oecd development concept working papers", "oecd development concepts working papers", "child development control working papers", "based development control working papers", "oecd development content working papers", "oecd development control working paper"
"oriented development control working papers" » "oriented development context working papers", "oriented development concept working papers", "oriented development concepts working papers", "oriented development content working papers", "oriented development control working paper"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"oecd development control working papers\") OR (\"oriented development control working papers\"))".
• Removing quotes may allow a broader search: (( oecd development control working papers ) OR ( oriented development control working papers )).
• Adding a wildcard symbol may retrieve word variants: (("oecd development control working papers") OR ("oriented development control working papers"))*.
