Unsigned long field type

Unsigned long is a numeric field type that represents an unsigned 64-bit integer with a minimum value of 0 and a maximum value of 264-1 (from 0 to 18446744073709551615 inclusive).

PUT my_index
{
  "mappings": {
    "properties": {
      "my_counter": {
        "type": "unsigned_long"
      }
    }
  }
}

Unsigned long can be indexed in a numeric or string form, representing integer values in the range [0, 18446744073709551615]. They can’t have a decimal part.

POST /my_index/_bulk?refresh
{"index":{"_id":1}}
{"my_counter": 0}
{"index":{"_id":2}}
{"my_counter": 9223372036854775808}
{"index":{"_id":3}}
{"my_counter": 18446744073709551614}
{"index":{"_id":4}}
{"my_counter": 18446744073709551615}

Term queries accept any numbers in a numeric or string form.

GET /my_index/_search
{
    "query": {
        "term" : {
            "my_counter" : 18446744073709551615
        }
    }
}

Range query terms can contain values with decimal parts. In this case Elasticsearch converts them to integer values: gte and gt terms are converted to the nearest integer up inclusive, and lt and lte ranges are converted to the nearest integer down inclusive.

It is recommended to pass ranges as strings to ensure they are parsed without any loss of precision.

GET /my_index/_search
{
    "query": {
        "range" : {
            "my_counter" : {
                "gte" : "9223372036854775808.5",
                "lte" : "18446744073709551615"
            }
        }
    }
}

For queries with sort on an unsigned_long field, for a particular document Elasticsearch returns a sort value of the type long if the value of this document is within the range of long values, or of the type BigInteger if the value exceeds this range.

GET /my_index/_search
{
    "query": {
        "match_all" : {}
    },
    "sort" : {"my_counter" : "desc"}
}
