I'm presently using this to get a high-level snapshot of index counts:
GET /_cat/indices?v&s=docs.count:desc
But it's displaying all documents included nested documents. I can't find any documentation on whether possible to also (or just) display the count of parent documents per index. For example, I have a store index:
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
yellow open store_20181024_082902 TFiAcSJEQkey5maZ1KTGWA 5 1 5825 215 1.1mb 1.1mb
But there are only something like 1184 store documents in this index. I suppose it's also possible to do a search for all records without enabling _source, but this only applies to a single index.
Thanks.
