Perhaps you should try some spelling variations:
"city management controls." » "city management contract.", "city management tools.", "city management functions.", "data management controls.", "crop management controls.", "security management controls."
"facility management based." » "liability management based.", "utility management based.", "quality management based.", "facility management case.", "facility management board.", "facility management issues."
"city management centers." » "city management water.", "city management entity.", "data management centers.", "crop management centers.", "security management centers."
"case management energy." » "case management entity.", "case management agency.", "change management energy.", "asset management energy.", "basin management energy."
"cash management concepts." » "asset management concepts."
"chain management a." » "chain management _."

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: (((((("case management energy.") OR ((((((("city management centers.") OR ("city management controls."))) OR ("facility management based."))) OR ("waste management control."))))) OR ((("chain management a.") OR ("cash management concepts."))))) OR ("debt management contracts."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"case management energy.\") or (((((((\"city management centers.\") OR (\"city management controls.\"))) or (\"facility management based.\"))) or (\"waste management control.\"))))) or (((\"chain management a.\") or (\"cash management concepts.\"))))) or (\"debt management contracts.\"))~".
• Removing quotes may allow a broader search: (((((( case management energy. ) or ((((((( city management centers. ) OR ( city management controls. ))) or ( facility management based. ))) or ( waste management control. ))))) or ((( chain management a. ) or ( cash management concepts. ))))) or ( debt management contracts. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("case management energy.") or ((((((("city management centers.") OR ("city management controls."))) or ("facility management based."))) or ("waste management control."))))) or ((("chain management a.") or ("cash management concepts."))))) or ("debt management contracts."))*.
