Perhaps you should try some spelling variations:
"a development reports" » "a development efforts", "a development results", "a development research", "_ development reports", "clean development reports", "city development reports"
"asian development reports" » "asian development efforts", "asian development results", "asian development research", "human development reports", "urban development reports", "clean development reports"
"a development report" » "_ development report", "clean development report", "city development report"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("a development reports") OR ("asian development reports"))) or ("a development report"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a development reports") OR ("asian development reports"))) OR ("a development report")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a development reports\") OR (\"asian development reports\"))) or (\"a development report\"))".
• Removing quotes may allow a broader search: (((( a development reports ) OR ( asian development reports ))) or ( a development report )).
• Adding a wildcard symbol may retrieve word variants: (((("a development reports") OR ("asian development reports"))) or ("a development report"))*.
