Perhaps you should try some spelling variations:
"e development programs." » "e development programme.", "e development projects.", "sme development programs.", "mine development programs.", "site development programs."
"clean development studies." » "clean development series.", "clean development services.", "clean development strategies.", "human development studies.", "urban development studies."
"e development process." » "e development projects.", "e development policies.", "sme development process.", "mine development process.", "site development process."

You may be able to get more results by adjusting your search query.

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