Hi [~markus17], the updated patch looks good. I'll open a PR for easier
merging. Alternatively, feel free to apply the patch to master and commit it!

It sounds plausible to reset the increased depth back to the default value if
the URL isn't matched.
Generally, I agree that steering a crawler and keep it focused is always
difficult. We also should update the plugin scoring-similarity, not sure
whether it's still working with a recent Hadoop and a quite old Mahout version
combined. Interestingly,
[SimilarityScoringFilter|https://cwiki.apache.org/confluence/display/NUTCH/SimilarityScoringFilter]
mentions the filtering of URLs/outlinks as a nice-to-have option.
