Hi,
Let's say I have 2 indices: \*one whose name is index\_name and an other
index with alias \*_index\_name (called second\_index)._
In this way there is a conflict.
_How ElasticSearch handles such situation?_
Does it give priority to the alias (this means when you are using
_index\_name_ it will refer to _second\_index_)?
Or does it do the opposite (this means when you are using _index\_name_ it
will refer to the first index called _index\_name_).

Basically there will be no conflict, because Elasticsearch does not allow
you to set an alias that is the same of an index name.
Solved!
Thanks 🙂
