Query for all indices in a cluster

Elastic Stack Elasticsearch
1

Hi,
In Elasticsearch 6.x, there is a call to es.indices.get_alias to get all the indices in a given alias. Is there a method to get all indices that are not associated with any alias. My purpose is to clean up those indices that are not associated with any alias.
Thanks,

Not that I'm aware of. You can get a list of all the indices (Cat Indices, Get Index, etc), but I can't think of an API that returns only the indices that don't have an associated alias.

I think you'll have to get the list of indices, then the list of aliases and their associated indices, and intersect the two sets client-side.

Thanks, I can use curl to get the indices as you suggested. Does it have any way to get indices that match a certain pattern in Python?

curl -X GET "localhost:9200/1234*"

I found out that you can get all the indices that match a pattern as
es.indices.get(index="1234*")
