Thanks! That did the trick! Although it required some more work in the
component level of generating the same query key as the index searcher
else when you go to try and fetch scores for a cached query result, I
got a lot of NPE since the stats are computed in the collector level
which for me isn't
I suggest to create a component, put it after QueryComponent. in prepare it
should add own PostFilter into list of request filters, your post filter
will be able to inject own DelegatingCollector, then you can just add
collected histogram into result named list
