[[cat-indices]]
=== cat indices
Returns high-level information about indices in a cluster.
[[cat-indices-api-request]]
==== {api-request-title}
`GET /_cat/indices/{index}`
[[cat-indices-api-desc]]
==== {api-description-title}
Use the cat indices API to get the following information for each index in a
cluster:
* Shard count
* Document count
* Deleted document count
* Primary store size
* Total store size of all shards, including shard replicas
These metrics are retrieved directly from
https://lucene.apache.org/core/[Lucene], which {es} uses internally to power
indexing and search. As a result, all document counts include hidden
<<nested,nested>> documents.
To get an accurate count of {es} documents, use the <<cat-count,cat count>> or
<<search-count,count>> APIs.
