Malini, I would suggest starting a new thread instead of adding to an old
one.
I find the Java API for the boost functions to be confusing, or at least,
not as clean as the rest of the Java API. I wonder if the Elasticsearch
team would accept a PR. Jörg's example above could be used as a skeleton
for your code. Something like
new FunctionScoreQueryBuilder(existingFilteredQuery)
.add(termsFilter("abbrev", "computer"), factorFunction(-10f))
