Perhaps you should try some spelling variations:
"a development studies." » "a development services.", "a development strategies.", "a development strategy.", "_ development studies.", "clean development studies.", "city development studies."
"asian development series." » "asian development services.", "asian development agencies.", "asian development africa.", "urban development series.", "clean development series.", "capital development series."
"human development series." » "human development services.", "human development agencies.", "human development africa."

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 studies.") or ((("asian development series.") OR ("human development series."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("a development studies.") OR ((("asian development series.") OR ("human development series."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"a development studies.\") or (((\"asian development series.\") OR (\"human development series.\"))))*".
• Removing quotes may allow a broader search: (( a development studies. ) or ((( asian development series. ) OR ( human development series. ))))*.
