Hello everyone, We're in the process of upgrading a service from Solr 4.4 to Solr 6. While comparing result quality between the two versions, I found that a result's phrase query score now contains the highest scoring field. In Solr 4.4, the sum of all matching fields' scores was added to the total score.
This behavior looks similar to how a tie breaker set to >0 impacts regular queries, although this does not appear to be documented. Is it possible that such a change was introduced between 4.4 and 6? I checked the change logs and documentation to no avail. Thanks! Chris
