Perhaps you should try some spelling variations:
"neoconservatism" » "neoconservative", "geoconservation", "neoconservation"
"neokonservative" » "neoconservative", "neoconservatives", "nonconservative", "neoconservation"
"neokonservativen" » "neoconservativen", "neoconservativesn", "nonconservativen", "neoconservative", "konservativen", "konservativer", "neoconservationn"
"neokonservatismusn" » "neokonservatismus", "neokonservativismus", "konservatismus"
"konservative" » "conservative", "conservation"
"conservatism" » "conservation", "conservative"

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 ("neokonservativen" OR "neokonservatismusn")) OR "konservative")) OR "conservatism").
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"neoconservatism\" or ((\"neokonservative\" or (\"neokonservativen\" OR \"neokonservatismusn\")) or \"konservative\")) or \"conservatism\")".
• Removing quotes may allow a broader search: (( neoconservatism or (( neokonservative or ( neokonservativen OR neokonservatismusn )) or konservative )) or conservatism ).
• Adding a wildcard symbol may retrieve word variants: (("neoconservatism" or (("neokonservative" or ("neokonservativen" OR "neokonservatismusn")) or "konservative")) or "conservatism")*.
