Range field types

Range field types represent a continuous range of values between an upper and lower bound. For example, a range can represent any date in October or any integer from 0 to 9. They are defined using the operators gt or gte for the lower bound, and lt or lte for the upper bound. They can be used for querying, and have limited support for aggregations. The only supported aggregations are histogram, cardinality.

The following range types are supported:

`integer_range`	A range of signed 32-bit integers with a minimum value of `-2³¹` and maximum of `2³¹-1`.
`float_range`	A range of single-precision 32-bit IEEE 754 floating point values.
`long_range`	A range of signed 64-bit integers with a minimum value of `-2⁶³` and maximum of `2⁶³-1`.
`double_range`	A range of double-precision 64-bit IEEE 754 floating point values.
`date_range`	A range of `date` values. Date ranges support various date formats through the `format` mapping parameter. Regardless of the format used, date values are parsed into an unsigned 64-bit integer representing milliseconds since the Unix epoch in UTC. Values containing the `now` date math expression are not supported.
`ip_range`	A range of ip values supporting either IPv4 or IPv6 (or mixed) addresses.

Below is an example of configuring a mapping with various range fields followed by an example that indexes several range types.

resp = client.indices.create(
    index="range_index",
    settings={
        "number_of_shards": 2
    },

                "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
            }
        }
    },
)

	`date_range` types accept the same field parameters defined by the `date` type.
	Example indexing a meeting with 10 to 20 attendees, not including 20.
	Example date range using date time stamp.

The following is an example of a term query on the integer_range field named "expected_attendees". 12 is a value inside the range, so it will match.

resp = client.search(
    index="range_index",
    query={
        "term": {
            "expected_attendees": {
                "value": 12
            }

console.log(response);

          }
        }
      }
    ]
  }
}

The following is an example of a date_range query over the date_range field named "time_frame".

resp = client.search(
    index="range_index",
    query={
        "range": {
            "time_frame": {
                "gte": "2015-10-31",
                "lte": "2015-11-01",
                "relation": "within"
            }
        }
    },
)
print(resp)

response = client.search(
  index: 'range_index',

    query: {
      range: {
        time_frame: {
          gte: '2015-10-31',
          lte: '2015-11-01',
          relation: 'within'
        }
      }
    }
  }
)
puts response

const response = await client.search({
  index: "range_index",
  query: {
    range: {
      time_frame: {
        gte: "2015-10-31",
        lte: "2015-11-01",
        relation: "within",
      },
    },
  },
});
console.log(response);

        "lte" : "2015-11-01",
        "relation" : "within" 
      }
    }
  }
}

	Range queries work the same as described in range query.
	Range queries over range fields support a `relation` parameter which can be one of `WITHIN`, `CONTAINS`, `INTERSECTS` (default).

This query produces a similar result:

{
  "took": 13,
  "timed_out": false,
  "_shards" : {
    "total": 2,
    "successful": 2,
    "skipped" : 0,
    "failed": 0
  },
  "hits" : {
    "total" : {
        "value": 1,
        "relation": "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "range_index",
        "_id" : "1",
        "_score" : 1.0,
        "_source" : {
          "expected_attendees" : {
            "gte" : 10, "lt" : 20
          },
          "time_frame" : {
            "gte" : "2015-10-31 12:00:00", "lte" : "2015-11-01"
          }
        }
      }
    ]
  }
}

IP Range

edit

In addition to the range format above, IP ranges can be provided in CIDR notation:

resp = client.indices.put_mapping(
    index="range_index",
    properties={
        "ip_allowlist": {
            "type": "ip_range"
        }
    },
)
print(resp)

resp1 = client.index(
    index="range_index",
    id="2",
    document={
        "ip_allowlist": "192.168.0.0/16"
    },
)
print(resp1)

response = client.indices.put_mapping(
  index: 'range_index',
  body: {
    properties: {
      ip_allowlist: {
        type: 'ip_range'
      }
    }
  }
)
puts response

response = client.index(
  index: 'range_index',
  id: 2,
  body: {
    ip_allowlist: '192.168.0.0/16'
  }
)
puts response

const response = await client.indices.putMapping({
  index: "range_index",
  properties: {
    ip_allowlist: {
      type: "ip_range",
    },
  },
});
console.log(response);

const response1 = await client.index({
  index: "range_index",
  id: 2,
  document: {
    ip_allowlist: "192.168.0.0/16",
  },
});
console.log(response1);

PUT range_index/_mapping
{
  "properties": {
    "ip_allowlist": {
      "type": "ip_range"
    }
  }
}

PUT range_index/_doc/2
{
  "ip_allowlist" : "192.168.0.0/16"
}

Parameters for range fields

edit

The following parameters are accepted by range types:

`coerce`	Try to convert strings to numbers and truncate fractions for integers. Accepts `true` (default) and `false`.
`doc_values`	Should the field be stored on disk in a column-stride fashion, so that it can later be used for sorting, aggregations, or scripting? Accepts `true` (default) or `false`.
`index`	Should the field be searchable? Accepts `true` (default) and `false`.
`store`	Whether the field value should be stored and retrievable separately from the `_source` field. Accepts `true` or `false` (default).

Synthetic `_source`

edit

Synthetic _source is Generally Available only for TSDB indices (indices that have index.mode set to time_series). For other indices synthetic _source is in technical preview. Features in technical preview may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

range fields support synthetic _source in their default configuration. Synthetic _source cannot be used with doc_values disabled.

Synthetic source always sorts values and removes duplicates for all range fields except ip_range . Ranges are sorted by their lower bound and then by upper bound. For example:

resp = client.indices.create(
    index="idx",
    mappings={
        "_source": {
            "mode": "synthetic"
        },
        "properties": {
            "my_range": {
                "type": "long_range"
            }
        }
    },
)
print(resp)

resp1 = client.index(
    index="idx",
    id="1",
    document={
        "my_range": [
            {
                "gte": 200,
                "lte": 300
            },
            {
                "gte": 1,
                "lte": 100
            },
            {
                "gte": 200,
                "lte": 300
            },
            {
                "gte": 200,
                "lte": 500
            }
        ]
    },
)
print(resp1)

response = client.indices.create(
  index: 'idx',
  body: {
    mappings: {
      _source: {
        mode: 'synthetic'
      },
      properties: {
        my_range: {
          type: 'long_range'
        }
      }
    }
  }
)
puts response

response = client.index(
  index: 'idx',
  id: 1,
  body: {
    my_range: [
      {
        gte: 200,
        lte: 300
      },
      {
        gte: 1,
        lte: 100
      },
      {
        gte: 200,
        lte: 300
      },
      {
        gte: 200,
        lte: 500
      }
    ]
  }
)
puts response

PUT idx
{
  "mappings": {
    "_source": { "mode": "synthetic" },
    "properties": {
      "my_range": { "type": "long_range" }
    }
  }
}

PUT idx/_doc/1
{
  "my_range": [
    {
        "gte": 200,
        "lte": 300
    },
    {
        "gte": 1,
        "lte": 100
    },
    {
        "gte": 200,
        "lte": 300
    },
    {
        "gte": 200,
        "lte": 500
    }
  ]
}

Will become:

{
  "my_range": [
    {
        "gte": 1,
        "lte": 100
    },
    {
        "gte": 200,
        "lte": 300
    },
    {
        "gte": 200,
        "lte": 500
    }
  ]
}

Values of ip_range fields are not sorted but original order is not preserved. Duplicate ranges are removed. If ip_range field value is provided as a CIDR, it will be represented as a range of IP addresses in synthetic source.

For example:

resp = client.indices.create(
    index="idx",
    mappings={
        "_source": {
            "mode": "synthetic"
        },
        "properties": {
            "my_range": {
                "type": "ip_range"
            }
        }
    },
)
print(resp)

resp1 = client.index(
    index="idx",
    id="1",
    document={

            {
                "gte": "10.0.0.0",
                "lte": "10.0.0.255"
            }
        ]
    },
)
print(resp1)

response = client.indices.create(
  index: 'idx',
  body: {
    mappings: {
      _source: {
        mode: 'synthetic'
      },
      properties: {

    }
  }

      {
        gte: '10.0.0.0',
        lte: '10.0.0.255'
      }
    ]
  }
)
puts response

PUT idx
{

    }

}

Range field vales are always represented as inclusive on both sides with bounds adjusted accordingly. Default values for range bounds are represented as null. This is true even if range bound was explicitly provided. For example:

resp = client.indices.create(
    index="idx",
    mappings={
        "_source": {
            "mode": "synthetic"
        },
        "properties": {
            "my_range": {
                "type": "long_range"
            }
        }
    },
)
print(resp)

resp1 = client.index(
    index="idx",
    id="1",
    document={
        "my_range": {
            "gt": 200,
            "lt": 300
        }
    },
)
print(resp1)

response = client.indices.create(
  index: 'idx',
  body: {
    mappings: {
      _source: {
        mode: 'synthetic'
      },
      properties: {
        my_range: {
          type: 'long_range'
        }
      }
    }
  }
)
puts response

response = client.index(
  index: 'idx',
  id: 1,
  body: {
    my_range: {
      gt: 200,
      lt: 300
    }
  }
)
puts response

PUT idx
{
  "mappings": {
    "_source": { "mode": "synthetic" },
    "properties": {
      "my_range": { "type": "long_range" }
    }
  }
}

PUT idx/_doc/1
{
  "my_range": {
    "gt": 200,
    "lt": 300
  }
}

Will become:

{
  "my_range": {
    "gte": 201,
    "lte": 299
  }
}

Default values for range bounds are represented as null in synthetic source. This is true even if range bound was explicitly provided with default value. For example:

resp = client.indices.create(
    index="idx",
    mappings={
        "_source": {
            "mode": "synthetic"
        },
        "properties": {
            "my_range": {
                "type": "integer_range"
            }
        }
    },
)
print(resp)

resp1 = client.index(
    index="idx",
    id="1",
    document={
        "my_range": {
            "lte": 2147483647
        }
    },
)
print(resp1)

PUT idx
