Jessica Cheng Mallet closed SOLR-6722.
--------------------------------------
Resolution: Won't Fix
We implemented our own plugin to handle the aggregation correctly using a
different field than maxScore.
> Distributed function query sumtotaltermfreq does not return correct
> aggregated result

> Key: SOLR-6722
> URL: https://issues.apache.org/jira/browse/SOLR-6722
> Project: Solr
> Issue Type: Bug
> Reporter: Jessica Cheng Mallet
> Labels: aggregate, distributed, function
>
> The relevancy function query sumtotaltermfreq uses maxScore to return its
> result. However, in distributed mode, "max" is the incorrect aggregation
> function for sumtotaltermfreq. Instead, the "sum" should be returned.
> For example, in the following break-down of 3 shards, we expect the
> sumtotaltermfreq to be 1802.0 + 1693.0 + 1693.0, but instead the overall
> query returns a maxScore of 1802.0, which is the max but not the answer we
> want, and the sum is not returned anywhere.
