Your filter only allows content/y/m/d/* it doesnt allow content/y/index.html
for instance. Also note that intermediate pages are not necessarily called
index.html

You need to allow httrack to scan down all the directories to get all the urls
(y,m,d) and then filter out everything but the politik.  Try
+*/content/*
-*/content/*/*/*/*/*
+*/politik/*

*[a,z,e,r,t,y] 	any letters among a,z,e,r,t,y
*[a-z] 	any letters
