Perhaps you should try some spelling variations:
islamischer fundamentalismus » religioser fundamentalismus
islamic fundamentalist » islamische fundamentalismus, islamischen fundamentalismus
islamic fundamentals » dynamics fundamentals, basic fundamentals, logic fundamentals
fundamentalism » fundamentales, fundamentally, fundamentale
fundamentalismus » fundamentalesus, fundamentallyus, fundamentaleus

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 fundamentals) OR (islamic fundamentalism))) OR (((((islamic fundamentalist) OR (islamischer fundamentalismus))) OR (islamic (fundamentalism OR fundamental))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((islamic fundamentals) OR (islamic fundamentalism))) or (((((islamic fundamentalist) or (islamischer fundamentalismus))) or (islamic (fundamentalism or fundamental)))))".
• Adding a wildcard symbol may retrieve word variants: ((((islamic fundamentals) OR (islamic fundamentalism))) or (((((islamic fundamentalist) or (islamischer fundamentalismus))) or (islamic (fundamentalism or fundamental)))))*.
