When we deleted the indexes, the data were just marked by deleted.
We can list all indexes to show status.
|
1 2 |
sudo curl 'localhost:9200/_cat/indices?v' |
It will show the health, index name, pri, rep, docs.count, docs.deleted, store.size, pri.store.size.

If we want to clear the deleted indexes, we can optimize it.
|
1 2 |
sudo curl -XPOST 'http://localhost:9200/_optimize' |
And it will reply this message.
|
1 2 |
{"_shards":{"total":310,"successful":155,"failed":0}} |
Then when we list all indexes again, we will see the deleted indexes are gone.
