Perhaps you should try some spelling variations:
"neoconservatism" » "neoconservative", "geoconservation", "neoconservation"
"aeroconservation" » "geoconservation", "areasconservation", "cryoconservation"
"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 (("aeroconservation" OR "konservatismus") OR "konservative")) OR "conservatism").
• Removing quotes may allow a broader search: (( neoconservatism or (( aeroconservation or konservatismus ) or konservative )) or conservatism ).
• Adding a wildcard symbol may retrieve word variants: (("neoconservatism" or (("aeroconservation" or "konservatismus") or "konservative")) or "conservatism")*.
