{
"type" : "illegal_argument_exception",
"reason" : "Fielddata is disabled on text fields by default. Set fielddata=true on [interests] 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."
}
],

},
"status" : 400
}

i think it is caused by some version change in default settings , so the doc needs improvement , add corresponding settings before this chapter :)
