UTF8 encoding is longer than the max length 32766

Question

I\'ve upgraded my Elasticsearch cluster from 1.1 to 1.2 and I have errors when indexing a somewhat big string.

{
  \"error\": \"IllegalArgumentException[Docu

If you really want not_analyzed on on the property because you want to do some exact filtering then you can use "ignore_above": 256

Here is an example of how I use it in php:

'mapping'    => [
    'type'   => 'multi_field',
    'path'   => 'full',
    'fields' => [
        '{name}' => [
            'type'     => 'string',
            'index'    => 'analyzed',
            'analyzer' => 'standard',
        ],
        'raw' => [
            'type'         => 'string',
            'index'        => 'not_analyzed',
            'ignore_above' => 256,
        ],
    ],
],

In your case you probably want to do as John Petrone told you and set "index": "no" but for anyone else finding this question after, like me, searching on that Exception then your options are:

• set "index": "no"
• set "index": "analyze"
• set "index": "not_analyzed" and "ignore_above": 256

It depends on if and how you want to filter on that property.
