Perhaps you should try some spelling variations:
"institutional cooperation" » "institutional coordination", "international cooperation", "institutional foundations"
"multinational operations" » "multinational corporations", "multinational corporation", "multifunctional operation"
"institutional operation" » "institutions operations", "institutional integration", "institutional interaction"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("multinational operations") or ((("institutional operation") OR ("institutional cooperation"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("multinational operations") OR ((("institutional operation") OR ("institutional cooperation")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"multinational operations\") or (((\"institutional operation\") OR (\"institutional cooperation\"))))".
• Removing quotes may allow a broader search: (( multinational operations ) or ((( institutional operation ) OR ( institutional cooperation )))).
• Adding a wildcard symbol may retrieve word variants: (("multinational operations") or ((("institutional operation") OR ("institutional cooperation"))))*.
