Subject Re: Different facet count between 7.7.1 and 8.1.1
Date Wed, 12 Jun 2019 22:08:36 GMT
Can you reproduce it from a clean 7.7.1 install? I mean, index N docs and then run the facet
query? Is it a distributed query or a single shard? Does an "optimize" change anything? Is
this DocValues strings?

zero counts where as for 8 we see the correct counts. So something seems fixed for a bug that
i was not aware of, although are unit tests rely heavily on correct facet counts.
