We have 2 indices - "event" and "event-001"
"event-001" is created by using ILM
Both the indices have the same alias "event\_"
It is used to fetch and update the data in the above 2 indices
Query:
GET event\_/_alias
Result:
{
"event-001" : {
"aliases" : {
"event_" : {
"is\_write\_index" : true
}
}
},
"event" : {
"aliases" : {
"event\_" : { }
}
}
}
Problem scenario:
When there's a record in the "event" index with "_id" as ab1 and it is not present "event-001"
I try to update the record using the alias index as below.
Query:
POST event_/\_update/ab1
{
"doc": {
"city": "vijayawada"
},
"doc\_as\_upsert": true
}
Instead of updating in the "event" index, it is adding a new entry in the newly created "event-001" index.
How can I update an index where a record is present?
Can you please help on this.

Using [ILM automatic rollover](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-rollover.html#ilm-automatic-rollover), [write\_index](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-aliases.html#indices-aliases-api-request-body) is automaticaly set to the new index. You can use [Update by query API](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update-by-query.html#docs-update-by-query-api-source) to update docs but upsert seems difficult.
