Dynamic templates in Elasticsearch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a dynamic template that matches all string fields.

Elasticsearch

{
  "mappings": {
    "dynamic_templates": [
      {
        "strings_as_keywords": {
          "match_mapping_type": "[1]",
          "mapping": {
            "type": "keyword"
          }
        }
      }
    ]
  }
}

💡 Hint

Common Mistakes

Using 'text' instead of 'string' for match_mapping_type.

Using 'keyword' which is a field type, not a match_mapping_type.

The match_mapping_type for string fields is string in dynamic templates.

medium

Complete the code to apply a dynamic template only to fields matching the pattern 'user_*'.

Elasticsearch

{
  "mappings": {
    "dynamic_templates": [
      {
        "user_fields": {
          "match": "[1]",
          "mapping": {
            "type": "text"
          }
        }
      }
    ]
  }
}

Auser

Buser.*

Cuser_*

Duser?

Attempts:

💡 Hint

Common Mistakes

Using '?' which matches a single character.

Using 'user' without wildcard, which matches only exact field name.

The match pattern uses wildcard syntax, so user_* matches all fields starting with 'user_'.

3fill in blank

hard

Fix the error in the dynamic template to set the type to 'date' for fields matching 'date_*'.

Elasticsearch

{
  "mappings": {
    "dynamic_templates": [
      {
        "dates": {
          "match": "date_*",
          "mapping": {
            "type": "[1]"
          }
        }
      }
    ]
  }
}

Adatetime

Btime

Ctimestamp

Ddate

Attempts:

💡 Hint

Common Mistakes

Using 'datetime' or 'timestamp' which are not valid Elasticsearch types.

Using 'time' which is not a valid field type.

The correct Elasticsearch field type for dates is date.

4fill in blank

hard

Fill both blanks to create a dynamic template that maps all numeric fields to type 'long' and disables indexing.

Elasticsearch

{
  "mappings": {
    "dynamic_templates": [
      {
        "long_numbers": {
          "match_mapping_type": "[1]",
          "mapping": {
            "type": "[2]",
            "index": false
          }
        }
      }
    ]
  }
}

Binteger

Dfloat

Attempts:

💡 Hint

Common Mistakes

Using 'integer' or 'float' instead of 'long' for long numbers.

Forgetting to disable indexing.

The match_mapping_type for long numbers is long, and the field type should also be set to long.

5fill in blank

hard

Fill all three blanks to create a dynamic template that matches fields ending with '_txt', maps them as 'text' type with 'english' analyzer, and disables norms.

Elasticsearch

{
  "mappings": {
    "dynamic_templates": [
      {
        "text_fields": {
          "match": "[1]",
          "mapping": {
            "type": "[2]",
            "analyzer": "[3]",
            "norms": false
          }
        }
      }
    ]
  }
}

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

A*_txt

Btext

Cenglish

Dkeyword

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'keyword' type instead of 'text'.

Using wrong match pattern without wildcard.

The match pattern *_txt matches fields ending with '_txt'. The type is text with the english analyzer and norms disabled.
