Reading from an alias which has two indexes

Elastic Stack Elasticsearch
1

Hi,
If i have two indexes under an alias say "Old Index" and "New Index". the
old index contains a doc identified by #doc1, version 1 and the i start
populating "new index" (and stop writing to old index). I then index a
updated version of #doc 1 to "New Index". Now "New Index" contains #doc1,
version 2.

Now, when i issue a read query to the alias (which ahs Old & New Index
under it), which version of the doc would it return, #doc 1, version 2?

Thanks for your prompt response.

Kumar Subramanian.

It'd probably return both, depends on what your query is.
