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

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