I'm applying a post-filter (in order to get aggregations only on the original query scope). There is however a need to find/display the hit count before this post-filter was applied (otherwise we have to cache hits/hits/total which is not entirely portable for what we do)
I can obviously do something silly like
ValueCountBuilder agg = AggregationBuilders.count("hitsPrePostFilter").field("_uid"); request = request.addAggregation(agg);
but that's not ideal as it incurs unnecessary processing.
So I was wondering if there's a mechanism to get, in the same request, the hit count for the core/original query scope, before the post-filter was applied.
