Not having docValues is actually why you got the error. When I encountered this error last year, I opened this issue: https://issues.apache.org/jira/browse/SOLR-8088 Lucene 5.0 eliminated something known as the FieldCache, which I believe happened in LUCENE-5666. I don't understand all the implications, but this affected Solr quite profoundly, and most of the problems were not discovered until well after the 5.0 version was released. Many of those problems are still present in Solr, because fixing them will not be easy. Adding docValues and reindexing will eliminate the error, but docValues cannot be added to a TextField type (tokenized field). You'll need to copy the data to another field with copyField in your schema, and that field will need to be a StrField type with docValues added. Another problem is that an untokenized field may produce different results than you are expecting, and in some cases those results might be completely unusable. Thanks, Shawn
