Perhaps you should try some spelling variations:
"a development process." » "a development projects.", "a development programs.", "a development policies.", "_ development process.", "asian development process.", "city development process."
"clean development process." » "clean development projects.", "clean development programs.", "clean development policies.", "human development process.", "urban development process.", "child development process."
"a development africa." » "_ development africa.", "asian development africa.", "city 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 africa.") or ((("a development process.") OR ("clean development process."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("a development africa.") OR ((("a development process.") OR ("clean development process.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"a development africa.\") or (((\"a development process.\") OR (\"clean development process.\"))))".
• Removing quotes may allow a broader search: (( a development africa. ) or ((( a development process. ) OR ( clean development process. )))).
• Adding a wildcard symbol may retrieve word variants: (("a development africa.") or ((("a development process.") OR ("clean development process."))))*.
