Hi Oliver, > My questions are: > > 1. Why are the overrided lengthNorm() (under Lucene410) or > computeNorm() (under Lucene350) methods not called during a searching > process?
Regardless of whether you override the method or not, Lucene framework calls the method during index time only because length norm can be calculated by using the number of tokens in the field, i.e. not need to call it search time. > 2. How and where is fieldNorm calculated? I think fieldNorm = lengthNorm * boost of the field.
