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