Perhaps you should try some spelling variations:
"employees-ownership & co-operatives" » "employees-ownership & co-operativen", "employees-ownership & co-cooperatives", "employees-ownership & co-imperatives", "employees-ownership & co-operations", "employees-ownership & co-operatings"
"employees-ownership & co-operative" » "employees-ownership & co-cooperative", "employees-ownership & co-operation", "employees-ownership & co-operating"

Try widening your search to All Fields.

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"employees-ownership & co-operatives\") OR (\"employees-ownership & co-operative\"))".
• Removing quotes may allow a broader search: (( employees-ownership & co-operatives ) OR ( employees-ownership & co-operative )).
• Adding a wildcard symbol may retrieve word variants: (("employees-ownership & co-operatives") OR ("employees-ownership & co-operative"))*.
