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

Try widening your search to All Fields.

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

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