English Please! "Field data loading is forbidden on [city]"}

Hey

Wow....elasticsearch..what is the below error in English.

Does kibana work? Given the lack of documentation seems seems very unstable.

I have data in ES, see it in kibana, should be able to chart...done! But not so.

Error: Request to Elasticsearch failed: {"error":{"root_cause":[{"type":"illegal_state_exception","reason":"Field data loading is forbidden on [city]"}],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":[{"shard":0,"index":"logstash-2016.06.19","node":"zjWi3w8xT6SYON_Q-JSpuA","reason":{"type":"illegal_state_exception","reason":"Field data loading is forbidden on [city]"}}]}}

Do you have a city.raw field?
