Hello,  
Is there a way to retrieve a value from an SNS message (via an input) and pass that same value to an Elastic input ?

No events exist when an input is constructed, so its configuration cannot reference the fields of an event. However, you can query Elasticsearch using a [filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-elasticsearch.html), and that _can_ reference events.

Thank you @Badger for your answer. The use of filter does not cover my need because I need to retrieve a list of identifiers and if I go through the filters, all the objects corresponding to the identifiers are added to the event or I need to 'have one event by identifier.
