yes, id is an unique field. I found following issue in Jira: https://issues.apache.org/jira/browse/LUCENE-6336
It says affected versions are 4.10.3, 5.0. I'm using Solr 6.1 and seeing this issue. You can recreate it by indexing those documents I shared and querying. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
