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