> Caused by: org.apache.lucene.index.IndexNotFoundException: no segments* file found in InfinispanDirectory{indexName='emails'}: files: []
> 	at org.apache.lucene.index.SegmentInfos$FindSegmentsFile.run(SegmentInfos.java:726)
> 	at org.apache.lucene.index.SegmentInfos$FindSegmentsFile.run(SegmentInfos.java:683)
> {noformat}
