Hey folks,
I’m using the [logstash-filter-elasticsearch](https://github.com/logstash-plugins/logstash-filter-elasticsearch) and I’d like to query using IDs ([IDs | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-ids-query.html)), and I find myself unable.
Does anyone have any idea on how to work around that? The problem I’m having is that I can’t interpolate an array into the query, you can only interpolate strings...

In the end, what gets sent in the HTTP request to Elasticsearch _is_ a string, so the question is: what form is your data currently in, and what string to you want to convert that to so that you can interpolate it?
