Perhaps you should try some spelling variations:
"neoconservatism" » "neoconservative", "geoconservation", "neoconservation", "neokonservative"
"neokonservative" » "neokonservativen", "neoconservative", "konservative"
"conservatism" » "conservation", "conservative", "konservative"

You may be able to get more results by adjusting your search query.

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