[jira] [Commented] (SOLR-12393) ExpandComponent only calculates the
score of expanded docs when sorted by score
[ https://issues.apache.org/jira/browse/SOLR-12393?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16952086#comment-16952086 ]
Munendra S N commented on SOLR-12393:
-------------------------------------
[^SOLR-12393.patch]
In the latest patch, I have changed the condition so that scores are populated when when sort = null or score desc (default). In both these cases, TopScoreDocCollector is used which always populates the scores.

One more thing I observed is that, {{maxScore}} is always {{NaN}} when scores are requested. For populating {{maxScore}} in case of non-default score, we might need to use {{MaxScoreCollector}}. In Any case, this is not handled as part of the patch. I will create new issue for this

> If you use the ExpandComponent to show expanded docs and if you want the score back (specified in "fl"), it will be NaN if the expanded docs are sorted by anything other than the default score descending.
