[jira] [Commented] (SOLR-10237) Poly-Fields should error if subfield has docValues=true

["David Smiley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-10237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15900120#comment-15900120 ] 

David Smiley commented on SOLR-10237:
-------------------------------------

I'm trying to understand the problem here.  {{solr.PointType}} (an x,y generic spatial field) supports DocValues in its coordinate fields so they can be used in ValueSource/"function queries"; or am I wrong here?

> DocValues aren’t really supported in poly-fields at this point, but they don’t complain if the schema definition of the subfield has docValues=true. This leaves the index in an inconsistent state, since the SchemaField has docValues=true but there are no DV for the field.
> Since this breaks compatibility, I think we should just emit a warning unless the subfield is an instance of {{PointType}}. With {{\[Int/Long/Float/Double/Date\]PointType}} subfields, this is particularly important, since they use {{IndexOrDocValuesQuery}}, that would return incorrect results.
