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

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