• If you are trying to use Boolean operators, they must be ALL CAPS: (((("crisis management entity.") OR ((("care management control.") OR ((((("cash management water.") OR ("bank management data."))) OR ("land management contractors."))))))) OR ("reform management concepts."))~.
• Removing quotes may allow a broader search: (((( crisis management entity. ) or ((( care management control. ) or ((((( cash management water. ) or ( bank management data. ))) or ( land management contractors. ))))))) or ( reform management concepts. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("crisis management entity.") or ((("care management control.") or ((((("cash management water.") or ("bank management data."))) or ("land management contractors."))))))) or ("reform management concepts."))*.
