In general, trying to impose a strict ordering by this kind of
boosting is a losing proposition. Any change to the underlying index
will alter the term and doc stats and your particular use-case won't
work at some point.
So I'd just go with a "constant score boost", see:
https://lucene.apache.org/
I further tried to understand the results I see since the idf value is
smaller higher boost is not helping. Can we ensure that idf value should
not impact the ordering.
