Error: Document contains at least one immense term in field

[Hilal]

Hi,

I am trying mapping and indexing with ES-5.0.0 and PHP. I did mapping on kibana and I started indexing with my php codes.(http://192.168.1.35:8080/indexleme.php?p=index)
It indexed but then it stopped.
My error:

  Fatal error:  Uncaught exception 
    'Elasticsearch\Common\Exceptions\BadRequest400Exception' with message 
    '{"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[NchqMHF][127.0.0.1:9300][indices:data/write/index[p]]"}],"type":"illegal_argument_exception","reason":"Document

Problem part of code on mapping:

PUT titub3/ihale/_mapping
{
  "properties": {
    "ParaBirim" : {
      "type" : "keyword"
    }
  }
}

ParaBirim : Values for this field:
YTL
TL,
1.035,00
..etc

What kind of this mapping should be? keyword or float or others?

Lucene doesn't allow terms that contain more than 32k bytes. You could work around this issue by setting a limit on the length of your keyword fields, eg.

PUT titub3/ihale/_mapping
{
  "properties": {
    "ParaBirim" : {
      "type" : "keyword",
      "ignore_above": 10000
    }
  }
}

This will make Elasticsearch ignore all terms whose UTF8 representation would be more than 10k bytes.
