Perhaps you should try some spelling variations:
"waste management authority." » "waste management quality."
"chain management entity." » "chain management energy.", "chain management activity.", "chain management quality."
"basin management contracts." » "business management contracts.", "asset management contracts."
"case management data." » "change management data.", "asset management data.", "bank management data.", "case management a.", "case management case."
"cash management control." » "asset management control."

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 data.") OR ((("chain management entity.") OR ("waste management authority."))))) OR ((("debt management activities.") OR ("cash management control."))))) OR ((((("basin management contracts.") OR ("crisis management contracts."))) OR ("risk management concepts."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"case management data.\") or (((\"chain management entity.\") or (\"waste management authority.\"))))) or (((\"debt management activities.\") or (\"cash management control.\"))))) or (((((\"basin management contracts.\") OR (\"crisis management contracts.\"))) or (\"risk management concepts.\"))))~".
• Removing quotes may allow a broader search: (((((( case management data. ) or ((( chain management entity. ) or ( waste management authority. ))))) or ((( debt management activities. ) or ( cash management control. ))))) or ((((( basin management contracts. ) OR ( crisis management contracts. ))) or ( risk management concepts. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((((("case management data.") or ((("chain management entity.") or ("waste management authority."))))) or ((("debt management activities.") or ("cash management control."))))) or ((((("basin management contracts.") OR ("crisis management contracts."))) or ("risk management concepts."))))*.
