Hello Team,

Is it possible to check if document with matching query is already available in the index? if yes use the indexed field value to set field in new document. If match is not found create a field with default value.  
I am trying elasticsearch filter plugin.  
Could you please let me know if there is any other options available to achieve this.

Elasticsearch and Logstash version is 6.3

Thank you,  
Aditya
