Searching more than one index in a query

Elastic Stack Elasticsearch
1

Hello All,

I want to write a query to search more than one index in my cluster is it possible or not?
Is there any way I can query more than one index in my single query ?

Yep - https://www.elastic.co/guide/en/elasticsearch/reference/current/multi-index.html

Hey Mark thanks for replying,
the link also states that,
Single index APIs such as the [Document APIs]) do not support multiple indices.
All CRUD APIs are single-index APIs. The index parameter accepts a single index name, or an alias which points to a single index.

And also is it possible to query all fields in all indices ?
