Perhaps you should try some spelling variations:
"politische reform" » "political reform", "politische rechte"
"politische reformen" » "political reformen", "politische rechteen"
"police reform" » "policy reform", "policy reforms", "political reform"

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: (((("politische reform") OR ("police reform"))) OR ("politische reformen"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"politische reform\") OR (\"police reform\"))) or (\"politische reformen\"))*".
• Removing quotes may allow a broader search: (((( politische reform ) OR ( police reform ))) or ( politische reformen ))*.
