Frozen Indices [sql-index-frozen]

By default, Elasticsearch SQL doesn’t search frozen indices. 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 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:
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

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.
