• Performing a fuzzy search may retrieve terms with similar spellings: (((((("bank management centers.") or ("demand management water."))) or ((("bank management control.") or ("risk management control."))))) or ((((("reform management concepts.") OR ("farm management concepts."))) or ("firm management concepts."))))~.

• Adding a wildcard symbol may retrieve word variants: (((((("bank management centers.") or ("demand management water."))) or ((("bank management control.") or ("risk management control."))))) or ((((("reform management concepts.") OR ("farm management concepts."))) or ("firm management concepts."))))*.
