Perhaps you should try some spelling variations:
"a development strategies." » "a development strategy.", "_ development strategies.", "clean development strategies.", "asian development strategies."
"a development studies." » "a development services.", "a development strategy.", "a development policies.", "_ development studies.", "clean development studies.", "asian development studies."
"world development series." » "world development services.", "world development agencies.", "world 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 ("a development strategies."))) or ("world development series."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("a development studies.") OR ("a development strategies."))) OR ("world development series."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a development studies.\") OR (\"a development strategies.\"))) or (\"world development series.\"))*".
• Removing quotes may allow a broader search: (((( a development studies. ) OR ( a development strategies. ))) or ( world development series. ))*.
