Yes. > 2. With useDocValuesAsStored=true and the following definition, will Solr > retrieve id from docValues instead of stored field? No. AFAIK, if you define both docValues="true" and stored="true" in your schema, Solr tries to retrieve stored value. (Except using streaming expressions or /export handler etc... See: https://lucene.apache.org/solr/guide/6_6/docvalues.html#DocValues-EnablingDocValues ) Thanks, Yasufumi 2018年11月6日(火) 9:54 Wei <weiwan...@gmail.com>: > Hi, > > I have a few questions about using the useDocValuesAsStored option to > retrieve field from docValues: > > 1.
