Hi ,
Mikhail Thanks , I looked at the explain and this is what I see for the two
different documents in questions, they have identical scores even though
the document 2 has a shorter productName field, I do not see any lenghtNorm
related information in the explain.
Also I am not exactly clear on what needs to be looked in the API ?
