Exception in elastic search console while searching for a product

org.elasticsearch.transport.RemoteTransportException: [f5duxzq][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 [categories] in order to load fielddata in memory
by uninverting the inverted index. Note that this can however use significant memory.

I also got the same exceptions, after lots of hours spend got the solutions. Use Elastic Search server 2.4.4 which works fine and resolved all other issue related search functionality.
