I am getting below error when I am trying to query :slight_smile :

Welcome to our community! :smiley:

What is the mapping of the index?
Also please format your code/logs/config using the </> button, or markdown style back ticks. It helps to make things easy to read which helps us help you :slight_smile:

Thanks mark

here is the mapping:

{
  "stores": {
    "mappings": {
      "properties": {
        "product": {
          "properties": {
            "product": {
              "type": "text",
              "fields": {
                "keyword": {
                  "type": "keyword",
                  "ignore_above": 256
                }
              }
            },
            "quantity": {
              "type": "long"
            }
          }
        },
        "suburb": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        }
      }
    }
  }
}

What version of Elasticsearch are you running?

version 8.6

Can you please get the mappings from the index you are querying? The mappings you specified seem to contain a mapping conflict (product field mapped both as object and string), which I believe should cause an error.

In order to run a nested query you need to have it nested in your mapping as well.
