My fault, but everything is successfully set up now.

I think I have reproduced the issue. The crawl is still running, but I 
guess it will stop very soon due to the following entries in my log. The 
last fetched URL before the first of these log entries below was: 
https://www.duo.uio.no/handle/123456789/31/discover?fq=author_filter%3Aaaberge%2C%5C+astrid%5C%7C%5C%7C%5C%7CAaberge%2C%5C+Astrid

It seems that this URL is part of a search, so maybe we will get around 
this problem by filtering out all search-related URLs. The problem is 
that it is already filtered out, but by doing post filtering. I can try 
to adjust that at next attempt.
