Hi,

I don't think this is possible as the elasticsearch input takes the query as an ElasticSearch DSL document.

However, there are a few possibilities that you could try:

1. If you have a platinum or enterprise license you are allowed to use the [ElasticSearch JDBC](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/sql-jdbc.html) agent. in this case, you could use the [jdbc-input](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-jdbc.html) plugin to do the query.
2. The second option is the Elasticsearch [SQL API](https://www.elastic.co/guide/en/elasticsearch/reference/current/sql-rest-overview.html). You could utilize this API using the [http\_poller](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-http_poller.html) plugin.

Best regards  
Wolfram
