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

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