The explanation of scores from the same document returned from 2 similar
queries differ in an unexpected way. There are 2 fields involved, 'contents'
and 'literals'. The 'literals' field has setBoost = 0. As you an see from
the explanations below, the total weight of the matching terms from the
'literal' field is 0. However, the weights produced by the matching terms in
the 'contents' field is very different, even with the same matching terms.
The reason is that the 'queryNorm' value is very different because the
'sumOfSquaredWeights' is very different. Why is this?
