Elasticsearch don't see my log logstash-2016.03.31


I've got problem with elasticsearch. I have run elasticsearch by Docker. By accident delete some folder with logs in /usr/share/elasticsearch/data/..../logstash-2016.03.31. Of course I've copy this folder but if I restore this folder my elasticsearch dot't see any logs form this day.

if i checked ES form console "curl 'localhost:9200/_cat/indices?v'" I see my index but his docs.count is 0.

Any suggestion ?
