org.elasticsearch.transport.RemoteTransportException: [H89-dk0][127.0.0.1:9300][indices:data/read/search[phase/query]]
Caused by: java.lang.IllegalArgumentException: Fielddata is disabled on text fields by default. Set fielddata=true on [message] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.
