• Performing a fuzzy search may retrieve terms with similar spellings: (((("reform management centers.") or ((("city management controls.") OR ("city management contract."))))) or ("reform management concepts."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("reform management centers.") OR ((("city management controls.") OR ("city management contract."))))) OR ("reform management concepts.")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"reform management centers.\") or (((\"city management controls.\") OR (\"city management contract.\"))))) or (\"reform management concepts.\"))".
• Removing quotes may allow a broader search: (((( reform management centers. ) or ((( city management controls. ) OR ( city management contract. ))))) or ( reform management concepts. )).
• Adding a wildcard symbol may retrieve word variants: (((("reform management centers.") or ((("city management controls.") OR ("city management contract."))))) or ("reform management concepts."))*.
