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