Hello,
I would like to do the join of two indexes based on an id column.
can i have an example ?
Elasticsearch does unfortunately not support query time joins. If this is a query you will need to run frequently you may need to find a workaround, e.g. by using a transform to create a separate index with joined up documents.
Someone might be able to provide some more detailed guidance if you provide additional details about your data, query and use case.
