# Frozen Indices [sql-index-frozen]
|
||
|
||
By default, Elasticsearch SQL doesn’t search [frozen indices](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-unfreeze). To search frozen indices, use one of the following features:
|
||
|
||
dedicated configuration parameter
|
||
: Set to `true` properties `index_include_frozen` in the [SQL search API](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-sql-query) or `index.include.frozen` in the drivers to include frozen indices.
|
||
|
||
dedicated keyword
|
||
: Explicitly perform the inclusion through the dedicated `FROZEN` keyword in the `FROM` clause or `INCLUDE FROZEN` in the `SHOW` commands:
|
||
|
||
```sql
|
||
SHOW TABLES INCLUDE FROZEN;
|
||
|
||
catalog | name | type | kind
|
||
---------------+---------------+----------+---------------
|
||
javaRestTest |archive |TABLE |FROZEN INDEX
|
||
javaRestTest |emp |TABLE |INDEX
|
||
javaRestTest |employees |VIEW |ALIAS
|
||
javaRestTest |library |TABLE |INDEX
|
||
```
|
||
|
||
```sql
|
||
SELECT * FROM FROZEN archive LIMIT 1;
|
||
|
||
author | name | page_count | release_date
|
||

Unless enabled, frozen indices are completely ignored; it is as if they do not exist and as such, queries ran against them are likely to fail.
