• If you are trying to use Boolean operators, they must be ALL CAPS: (((("springer science business model") OR ((("stronger science using model") OR ("astronomy science using model"))))) OR ("springer springe business models"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"springer science business model\") or (((\"stronger science using model\") OR (\"astronomy science using model\"))))) or (\"springer springe business models\"))*".
• Removing quotes may allow a broader search: (((( springer science business model ) or ((( stronger science using model ) OR ( astronomy science using model ))))) or ( springer springe business models ))*.
