• If you are trying to use Boolean operators, they must be ALL CAPS: (((("web site / authoring programs") OR ((("web site / authority program") OR ("web site / authority problems"))))) OR ("web site / authoring program")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"web site / authoring programs\") or (((\"web site / authority program\") OR (\"web site / authority problems\"))))) or (\"web site / authoring program\"))".
• Removing quotes may allow a broader search: (((( web site / authoring programs ) or ((( web site / authority program ) OR ( web site / authority problems ))))) or ( web site / authoring program )).
• Adding a wildcard symbol may retrieve word variants: (((("web site / authoring programs") or ((("web site / authority program") OR ("web site / authority problems"))))) or ("web site / authoring program"))*.
