Perhaps you should try some spelling variations:
"coimperatives marketing" » "cooperative marketing", "comparative marketing", "kooperatives marketing"
"cooperatives marketing" » "cooperative marketing", "kooperatives marketing", "kooperative marketing", "cooperativen marketing", "coimperatives marketing"
"operatives marketing" » "operative marketing", "operativen marketing", "imperatives marketing"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("operatives marketing") OR ((("cooperatives marketing") OR ("coimperatives marketing"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"operatives marketing\") or (((\"cooperatives marketing\") OR (\"coimperatives marketing\"))))*".
• Removing quotes may allow a broader search: (( operatives marketing ) or ((( cooperatives marketing ) OR ( coimperatives marketing ))))*.
