Enabling File Data while using _bulk API

Elastic Stack Elasticsearch
1

Hi all,
I am elastic search beginner and i am stuck in the following code. Please Help me out
POST /cars/transactions/_bulk
{ "index": {}}
{ "price" : 10000, "color" : "red", "make" : "honda", "sold" : "2014-10-28" }
{ "index": {}}
{ "price" : 20000, "color" : "red", "make" : "honda", "sold" : "2014-11-05" }
{ "index": {}}
{ "price" : 30000, "color" : "green", "make" : "ford", "sold" : "2014-05-18" }
{ "index": {}}
{ "price" : 15000, "color" : "blue", "make" : "toyota", "sold" : "2014-07-02" }
{ "index": {}}
{ "price" : 12000, "color" : "green", "make" : "toyota", "sold" : "2014-08-19" }
{ "index": {}}
{ "price" : 20000, "color" : "red", "make" : "honda", "sold" : "2014-11-05" }
{ "index": {}}
{ "price" : 80000, "color" : "red", "make" : "bmw", "sold" : "2014-01-01" }
{ "index": {}}
{ "price" : 25000, "color" : "blue", "make" : "ford", "sold" : "2014-02-12" }

GET /cars/transactions/_search
{
    "size" : 0,
    "aggs" : { 
        "popular_colors" : { 
            "terms" : { 
              "field" : "color"
            }
        }
    }
}

While using the above code I get the following error:
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [color] 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."

Please tell me how to fix this

Please format your code using </> icon as explained in this guide. It will make your post more readable.

Or use markdown style like:

You need to change the mapping I guess. What is your mapping look like?

GET /cars/_mapping

    {
  "cars": {
    "mappings": {
      "transactions": {
        "properties": {
          "color": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "fielddata": {
            "type": "boolean"
          },
          "make": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "price": {
            "type": "long"
          },
          "sold": {
            "type": "date"
          }
        }
      }
    }
  }
}

This is the result generated with GET /cars/_mapping

Then run the aggregation on color.keyword instead.

BTW I suspect you did something wrong when I see this line:

          "fielddata": {
            "type": "boolean"
          },

You probably tried to push a document although you wanted to update the mapping.

Thankyou David using color.keyword worked in this case. But can you please tell me why are we using color.keyword instead of color. This would help me in future

To run aggregations you need to use a keyword type field. Read https://www.elastic.co/guide/en/elasticsearch/reference/5.6/keyword.html

Thanks David for resolving my query. :smiley:
