Dynamic templates¶

Map whole numbers to integer instead of long¶

PUT /dynamic_template_test
{
  "mappings": {
    "dynamic_templates": [
      {
        "integers": {
          "match_mapping_type": "long",
          "mapping": {
            "type": "integer"
          }
        }
      }
    ]
  }
}

Test the dynamic template¶

Modify default mapping for strings (set ignore_above to 512)¶

{
  "mappings": {
    "dynamic_templates": [
      {
        "strings": {
          "match_mapping_type": "string",
          "mapping": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 512
              }

          }
        }
      }
    ]
  }

{
  "mappings": {
    "dynamic_templates": [
      {
        "strings_only_text": {
          "match_mapping_type": "string",
          "match": "text_*",
          "unmatch": "*_keyword",
          "mapping": {
            "type": "text"
          }
        }
      },
      {

          "match_mapping_type": "string",
          "match": "*_keyword",
          "mapping": {
            "type": "keyword"
          }
        }
      }
    ]
  }
}

POST /test_index/_doc
{

Setting match_pattern to regex¶

PUT /test_index
{
  "mappings": {
    "dynamic_templates": [
      {
        "names": {
          "match_mapping_type": "string",
          "match": "^[a-zA-Z]+_name$",
          "match_pattern": "regex",
          "mapping": {
            "type": "text"
          }
        }
      }
    ]
  }
}

POST /test_index/_doc
{
  "first_name": "John",
  "middle_name": "Edward",
  "last_name": "Doe"
}

Using path_match¶

PUT /test_index
{
  "mappings": {
    "dynamic_templates": [
      {
        "copy_to_full_name": {
          "match_mapping_type": "string",
          "path_match": "employer.name.*",
          "mapping": {
            "type": "text",
            "copy_to": "full_name"
          }
        }
      }
    ]
  }
}

POST /test_index/_doc
{
  "employer": {

          "match_mapping_type": "*",
          "mapping": {
            "type": "{dynamic_type}",
            "index": false
          }
        }
      }
