Thank you, Markus, At current rate, I just want this to work. I have no idea whether I want to omitNorms or not. At the moment of writing, I don't feel like that, anyway. More importantly, I want to boost pages which site field is www.example.com over blog.example.com, but without omitting hits on blog.example.com.
The query boost seems to filter out hits from blog.example.com completely, so that is not what I want. Abusing the boost field might be a nice idea. Can you please show me an example, presuming I don't really understand the connection between all the xml files and binaries. Not even really which one of solr and nutch is responsible for which task... :) 2011/8/31 Markus Jelsma <[email protected]> > Index-time boosting is not something very common and raises issues if you > want > to omitNorms in Solr. > > In Solr DisMax you can use a bq (boost query) to boost site:example.com > ^10. > All results that match the boost query receive a ^10 boost.
