The plugins directory only contains two scoring plugs: scoring-link and scoring-opic. What about the newscoring, linkrank, etc.? Where are they available?
Again, I'm confused about the nature/purpose of such scoring: 1. Does it work as a sorting function for the frontier of the crawling? --> this seems reasonable. 2. Or does it affect relevance in retrieval? If so, why is it handled in the crawler, but not solr? I'd greatly appreciate any enlightment.
