Perhaps you should try some spelling variations:
"e development policies." » "e development policy.", "e development projects.", "sme development policies.", "mine development policies.", "site development policies."
"_ development studies." » "_ development series.", "_ development services.", "_ development strategies."
"e development agencies." » "sme development agencies.", "mine development agencies.", "site development agencies."

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