Thanks for the answer.
I tried to further understand the weight and score mechanism when
running a
span query search.
I noticed that indeed the SpanScorer and SpanWeight are being called
and
some score is returned but it seems to me that these basic
implementations
are more appropriate for the basic SpanTermQuery.
For the other types of span queries, the inner queries scores and
weights
are not taken into account - for example if I run a simple
SpanOrQuery and
boost one of it's child SpanTermQuery, the boost is not taken into
account.
It seems to me that some recursive calculation is required in order
to take
into account all the weights and scores of the span's sub queries.
I'm trying to come up with a correct implementation for SpanOrQuery,
SpanNearQuery, SpanNotQuery based on similiar calculations of
BooleanQuery.
Do you have a better idea on how to achieve the correct scoring? the
score
calculations are quite complex for each case of span queries so any
help is
appreciated.
This will need to be implemented. It's funny, but I didn't realize
this was the case until the other day when I was looking deeper into
payload capabilities.
