• If you are trying to use Boolean operators, they must be ALL CAPS: (((("demand management readers.") OR ("oxford management reform."))) OR ((("oxford management controls.") OR ("reform management controls."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"demand management readers.\") or (\"oxford management reform.\"))) or (((\"oxford management controls.\") OR (\"reform management controls.\"))))~".
• Removing quotes may allow a broader search: (((( demand management readers. ) or ( oxford management reform. ))) or ((( oxford management controls. ) OR ( reform management controls. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("demand management readers.") or ("oxford management reform."))) or ((("oxford management controls.") OR ("reform management controls."))))*.
