Perhaps you should try some spelling variations:
"fund management activity." » "fund management activities.", "fund management facility.", "fund management authority.", "land management activity.", "demand management activity."
"cash management contracts." » "asset management contracts."
"farm management a." » "bank management a.", "data management a.", "forest management a."
"farm management _." » "bank management _.", "data management _.", "forest management _."
"city management how." » "data management how.", "case management how.", "crop management how.", "city management from."
"care management how." » "case management how.", "fire management how.", "change management how.", "care management from."
"firm management case." » "fire management case.", "fishery management case.", "forest management case."

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: (((((((("risk management control.") OR ("cash management contracts."))) OR ("fund management activity."))) OR ((("firm management case.") OR ((((("farm management a.") OR ("farm management _."))) OR ((("city management how.") OR ("care management how."))))))))) OR ("reform management tools."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"risk management control.\") or (\"cash management contracts.\"))) or (\"fund management activity.\"))) or (((\"firm management case.\") or (((((\"farm management a.\") OR (\"farm management _.\"))) or (((\"city management how.\") or (\"care management how.\"))))))))) or (\"reform management tools.\"))~".
• Removing quotes may allow a broader search: (((((((( risk management control. ) or ( cash management contracts. ))) or ( fund management activity. ))) or ((( firm management case. ) or ((((( farm management a. ) OR ( farm management _. ))) or ((( city management how. ) or ( care management how. ))))))))) or ( reform management tools. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((((("risk management control.") or ("cash management contracts."))) or ("fund management activity."))) or ((("firm management case.") or ((((("farm management a.") OR ("farm management _."))) or ((("city management how.") or ("care management how."))))))))) or ("reform management tools."))*.
