Perhaps you should try some spelling variations:
"basin management issues." » "chain management issues.", "business management issues.", "crisis management issues."
"basin management case." » "chain management case.", "business management case.", "crisis management case."
"asset management contracts." » "debt management contracts."
"case management fees." » "waste management fees.", "change management fees.", "chain management fees.", "case management fee.", "case management areas.", "case management from."
"city management framework." » "crop management framework.", "security management framework.", "facility management framework."
"data management a." » "debt management a.", "bank management a.", "demand management a.", "data management _."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("case management fees.") or ((("risk management control.") or ((("city management framework.") OR ("cash management framework."))))))) or ((((("data management a.") or ((("basin management issues.") or ("basin management case."))))) or ("asset management contracts."))))) or ("land management concepts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("case management fees.") OR ((("risk management control.") OR ((("city management framework.") OR ("cash management framework."))))))) OR ((((("data management a.") OR ((("basin management issues.") OR ("basin management case."))))) OR ("asset management contracts."))))) OR ("land management concepts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"case management fees.\") or (((\"risk management control.\") or (((\"city management framework.\") OR (\"cash management framework.\"))))))) or (((((\"data management a.\") or (((\"basin management issues.\") or (\"basin management case.\"))))) or (\"asset management contracts.\"))))) or (\"land management concepts.\"))".
• Removing quotes may allow a broader search: (((((( case management fees. ) or ((( risk management control. ) or ((( city management framework. ) OR ( cash management framework. ))))))) or ((((( data management a. ) or ((( basin management issues. ) or ( basin management case. ))))) or ( asset management contracts. ))))) or ( land management concepts. )).
• Adding a wildcard symbol may retrieve word variants: (((((("case management fees.") or ((("risk management control.") or ((("city management framework.") OR ("cash management framework."))))))) or ((((("data management a.") or ((("basin management issues.") or ("basin management case."))))) or ("asset management contracts."))))) or ("land management concepts."))*.
