medium

Complete the code to define a binary field in an Elasticsearch mapping.

Elasticsearch

💡 Hint

Common Mistakes

Using 'text' or 'keyword' type for binary data.

Using 'boolean' type instead of binary.

The binary type is used to store base64-encoded binary data in Elasticsearch.

3fill in blank

hard

Fix the error in the mapping to correctly define a boolean field.

Elasticsearch

{
  "mappings": {
    "properties": {
      "is_enabled": { "type": "[1]" }
    }
  }
}

Common Mistakes

Using 'bool' instead of 'boolean'.

Using 'text' or 'binary' for boolean fields.

The correct type for boolean fields in Elasticsearch is boolean, not 'bool'.

4fill in blank

hard

Fill both blanks to define a binary field with doc_values disabled.

Elasticsearch

{
  "mappings": {
    "properties": {
      "image_data": {
        "type": "[1]",
        "[2]": false
      }
    }
  }
}

💡 Hint

Common Mistakes

Using 'boolean' instead of 'binary' for binary data.

Using 'store' instead of 'doc_values' to disable storage.

The binary type stores base64 data, and doc_values can be disabled for it to save memory.

5fill in blank

hard

Fill all three blanks to define a boolean field with a default value and doc_values enabled.

Elasticsearch

{
  "mappings": {
    "properties": {
      "is_verified": {
        "type": "[1]",
        "[2]": true,
        "[3]": true
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'binary' instead of 'boolean' for boolean fields.

Confusing 'null_value' with 'doc_values'.

The field type is boolean. doc_values enables efficient sorting and aggregations. null_value sets a default when the field is missing.
