Subject understanding queryNorm
Date Sat, 03 Jan 2009 03:32:27 GMT

Hi,
   i wanted to understand  how the queryNorm is calculated. i did read similarity documentation
of lucene it says it is 


1
               
                  每每每每每每每每每每每每每每
               
               sqrt(sumOfSquaredWeights)

sumOfSquaredWeights   =  
            q.getBoost() 2
             ﹞ 
          
          
            ﹉
          
          
            (
            idf(t)  ﹞ 
            t.getBoost()
            ) 2
 

what would be default q.getBoost() ?  ( as i am not giving any value specifically any where
in solr). t.getBoost() is 1 in my case as i am not boosting any term at query time. can some
one explain with an example if you could ? 

thank you,
vinay
