David Smiley commented on SOLR-10843:
-------------------------------------
I think you mean enable docValues _by default_ for boolean fields?
I think that's addressed on another issue and I have a reason why _not_ to:
https://issues.apache.org/jira/browse/SOLR-10808?focusedCommentId=16041413&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16041413
LatLonPointSpatialField (The newer class for the "location" field in more
recent Solr versions) most definitely supports docValues. It's how distance
sorting/boosting works. I'm not sure if stored=false works on it but docValues
true (for using docValues for retrieval); maybe you'd like to tell us. What
apparently does not is streaming expressions on this field.

> Project: Solr
> Issue Type: Task
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Schema and Analysis
> Affects Versions: 6.6
> Reporter: kiran
> Priority: Minor
>
> * Doc values should be enabled for 'boolean' types in the example schemas.
> (I don't see a reason to why not because it is enabled for all supported
> field types)
> * Doc values should be disabled for 'location' field type since it is not
> supported
> From the sample schema:
> {code}
> <fieldType name="location" class="solr.LatLonPointSpatialField"
> docValues="true"/>
> {code}
> The code returns error message when fields of these types are accessed
> through export handler
> {code}
