Hi there, I'm attempting to use Elasticsearch to index JSON files that are comprised of multiple "test" fields ("test1", "test2", etc.), where each file represents a series of tests done on a single device. As I run later tests, I need to be able to add them as new fields to files that are already indexed. Is there a way to append to an indexed file in Elasticsearch? I am doing this through Filebeat and Logstash. Thank you!
