Perhaps you should try some spelling variations:
"_ development studies." » "_ development services.", "_ development strategies.", "_ development strategy."
"a development series." » "a development services.", "a development agencies.", "a development strategies."
"city development series." » "city development services.", "city development agencies.", "city development strategies.", "capacity development series.", "policy development series.", "community development series."

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