Perhaps you should try some spelling variations:
"basic business case" » "bass business case", "asia business case", "based business case", "basic business cycle", "basic business climate"
"basic business costs" » "bass business costs", "asia business costs", "based business costs", "basic business customs", "basic business centers"
"basic business cases" » "bass business cases", "asia business cases", "based business cases", "basic business cycles", "basic business licenses", "basic business climates"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("basic business case") OR ((("basic business costs") OR ("basic business cases"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"basic business case\") OR (((\"basic business costs\") OR (\"basic business cases\"))))*".
• Removing quotes may allow a broader search: (( basic business case ) OR ((( basic business costs ) OR ( basic business cases ))))*.
