------------------------------------------
Summary: 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
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.
