Perhaps you should try some spelling variations:
"e development studies." » "e development series.", "e development services.", "e development strategies.", "_ development studies.", "sme development studies.", "mine development studies."
"asian development policy." » "human development policy.", "urban development policy.", "clean development policy."
"a development policy." » "_ development policy.", "clean development policy.", "city development policy."

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

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