Sorta, but it is not the complete picture. Things gets complicated when you mix it with stored, so that you have "stored=true docValues=true". There's an article about that at https://sease.io/2020/03/docvalues-vs-stored-fields-apache-solr-features-and-performance-smackdown.html BTW: The documentation should definitely mention that stored preserves order & duplicates. It is not obvious. - Toke Eskildsen, Royal Danish Library
