Perhaps you should try some spelling variations:
"city management functions." » "city management operations.", "city management practices.", "city management education.", "data management functions.", "case management functions.", "crop management functions."
"city management controls." » "city management contract.", "city management tools.", "city management protocols.", "data management controls.", "case management controls.", "crop management controls."
"crisis management concepts." » "risk management concepts."
"cash management board." » "cash management case.", "cash management data.", "cash management how.", "asset management board."
"fire management contracts." » "side management contracts.", "case management contracts.", "zone management contracts."
"cash management a." » "asset management a."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((((("fire management contracts.") or ((("city management controls.") OR ("city management functions."))))) or ("debt management control."))) or ((("chain management _.") or ((("cash management a.") or ("cash management board."))))))) or ("crisis management concepts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("fire management contracts.") OR ((("city management controls.") OR ("city management functions."))))) OR ("debt management control."))) OR ((("chain management _.") OR ((("cash management a.") OR ("cash management board."))))))) OR ("crisis management concepts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"fire management contracts.\") or (((\"city management controls.\") OR (\"city management functions.\"))))) or (\"debt management control.\"))) or (((\"chain management _.\") or (((\"cash management a.\") or (\"cash management board.\"))))))) or (\"crisis management concepts.\"))".
• Removing quotes may allow a broader search: (((((((( fire management contracts. ) or ((( city management controls. ) OR ( city management functions. ))))) or ( debt management control. ))) or ((( chain management _. ) or ((( cash management a. ) or ( cash management board. ))))))) or ( crisis management concepts. )).
• Adding a wildcard symbol may retrieve word variants: (((((((("fire management contracts.") or ((("city management controls.") OR ("city management functions."))))) or ("debt management control."))) or ((("chain management _.") or ((("cash management a.") or ("cash management board."))))))) or ("crisis management concepts."))*.
