Hi Markus, I am also interested in using different regex-urlfilter for Generate step because I need to crawl only homepage of 10 websites continuously and index all links which are in the homepage but not go crawling recursively. I think it can be done by puting in regex-urlfilter file for generate only these 10 websites, And in other steps(fetch, updated, invertlinks, index) to use the default regex-urlfilter. As I see you said that is possible to have different nutch-site configs for each step. How can I configure to have another nutch-site config file for generate step and another nutch-site config file for other steps? Should I change code for this or is just a configuration trick?
Please help me for this. I really need it.

You can have different nutch-site configs where each has a different setting for urlfilter.regex.file, pointing to the relevant regex- urlfilter file. Or you can just copy regex-urlfilter-<JOB>.txt to regex- urlfilter.txt before executing that job.
