Perhaps you should try some spelling variations:
"sme development studies." » "sme development series.", "sme development services.", "sme development strategies.", "_ development studies.", "a development studies.", "asian development studies.", "sm_ development studies.", "sma development studies.", "smsite development studies."
"mine development africa." » "asian development africa.", "trade development africa.", "based development africa.", "min_ development africa.", "mina development africa.", "minsite development africa."
"e development africa." » "_ development africa.", "a development africa.", "site 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: (("sme development studies.") or ((("e development africa.") OR ("mine development africa."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("sme development studies.") OR ((("e development africa.") OR ("mine development africa.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sme development studies.\") or (((\"e development africa.\") OR (\"mine development africa.\"))))".
• Removing quotes may allow a broader search: (( sme development studies. ) or ((( e development africa. ) OR ( mine development africa. )))).
• Adding a wildcard symbol may retrieve word variants: (("sme development studies.") or ((("e development africa.") OR ("mine development africa."))))*.
