ranking in nutch/solr results

[al...@aim.com]

Hello,

I use nutch-1.2 with solr 1.4. Recently, I noticed that for search for a domain name, for example yahoo.com, yahoo.com is not in the first place. Instead other sites that has in content yahoo.com, are in the first places. I tested this issue with google. In its results domain is in the first place.

Any idea how to fix this in Nutch/Solr results.

Thanks in advance.
Alex.

Also you can use dismax in solr to setup weights for different fields, for
example, give url/id more weights than title and content.

It is called navigational query. 
You should implement custom ranking function for boosting correct sites.
Also query should be classified as navigational
