The suggestion to use a filter was [here](https://discuss.elastic.co/t/logstash-fingerprint-hash-everything/77827/2). [This](https://discuss.elastic.co/t/how-to-concatenate-fields-inside-an-array-using-logstash/100148/2) post solves a different problem, but shows you how to get the event data and to add a field. Now you just need add code to iterate over the fields.
