             Summary: Solr example schemas inaccurate comments on  docValues and StrField
                 Key: SOLR-11306
                 URL: https://issues.apache.org/jira/browse/SOLR-11306
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: examples
    Affects Versions: 6.6, 7.0
            Reporter: Tom Burton-West
            Priority: Minor


Several of the example managed-schema files have an outdated comment about docValues and StrField.  In Solr 6.6.0 these are under solr-6.6.0/solr/server and the lines where the comment starts for each file are:
solr/configsets/basic_configs/conf/managed-schema:216:   
solr/configsets/data_driven_schema_configs/conf/managed-schema:221:    
solr/configsets/sample_techproducts_configs/conf/managed-schema:317

In the case of Solr-6.6.0/server/solr/configsets/basic_configs/conf/managed-schema, shortly after the comment  are some lines which seem to directly contradict the comment:

216      <!-- The StrField type is not analyzed, but indexed/stored verbatim.
   217         It supports doc values but in that case the field needs to be
   218         single-valued and either required or have a default value.
   219        -->

On line 221 a StrField is declared with docValues that is multiValued:
221      <fieldType name="strings" class="solr.StrField" sortMissingLast="true" multiValued="true" docValues="true" />

Also note that the comments above say that the field must either be required or have a default value, but line 221 appears to satisfy neither condition.

The JavaDocs indicate that StrField can be multi-valued https://lucene.apache.org/core/6_6_0//core/org/apache/lucene/index/DocValuesType.html
