I agree that the doc could be better, but I still take issue with the earlier use of the phrase "proof-of-concept". If there are dozens of sites using it in production, several of them indexing 100's of millions of pages, I don't know how you can call it "proof-of-concept".
Honestly, I'm not sure if there's any other choice for a scalable open source search engine. Last I checked most of the other free projects were better suited to small site searches -- nothing on the scale of tens of millions of pages. So kudos, Nutch developers! Howie
