> When improving data-driven mode in SOLR-9526 we discussed back and forth whether to set {{useDocValuesAsStored}} for the {{*_str}} copy of text fields. This dynamic field is currently defined as
> {code:xml}
> <dynamicField name="*_str" type="strings" stored="false" docValues="true" indexed="false" />{code}
> Having lived with the current setting since 7.0, I think it is too noisy to return all the _str fields since this is redundant content from the analysed original field. Thus I propose to do as [~hossman] initially suggested, and explicitly set it to false starting from 7.4:
> {code:xml}
> <dynamicField name="*_str" type="strings" stored="false" indexed="false" docValues="true" useDocValuesAsStored="false" />
> {code}
> Note that this does not change how things are stored, only whether to display these by default. The {{*_str}} fields will still be available for sorting, faceting etc.
