using ElasticSearch and Kibana 5.1.1 for timeseries data. I've made field mapping according to https://www.elastic.co/blog/elasticsearch-as-a-time-series-data-store, where author encourages not to use index on those fields, as they wont be queryable, but aggregations should be fine.
But with this mapping, or even if I use type=keyword and index=false (to be up to date with ES 5.x), all the index=false/no fields Kibana displays as non-searchable and non-aggregatable.
Is this mapping wrong or is it Kibana? Because I can run aggregations for those data without any problem.
