Perhaps you should try some spelling variations:
islamic fundamentalist » islamische fundamentalismus, islamischer fundamentalismus, islamischen fundamentalismus
"islamic fundamentally" » "isac fundamental"
islamic fundamentales » dynamics fundamentals, basic fundamentals, logic fundamentals
"islamic fundamentalism" » "islamic fundamentals", "islamic fundamental", "islamic fundamentale"

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