Numeric datatypes

edit

The following numeric types are supported:

`long`	A signed 64-bit integer with a minimum value of `-2⁶³` and a maximum value of `2⁶³-1`.
`integer`	A signed 32-bit integer with a minimum value of `-2³¹` and a maximum value of `2³¹-1`.
`short`	A signed 16-bit integer with a minimum value of `-32,768` and a maximum value of `32,767`.
`byte`	A signed 8-bit integer with a minimum value of `-128` and a maximum value of `127`.
`double`	A double-precision 64-bit IEEE 754 floating point.
`float`	A single-precision 32-bit IEEE 754 floating point.

Below is an example of configuring a mapping with numeric fields:

PUT my_index
{
  "mappings": {
    "my_type": {
      "properties": {
        "number_of_bytes": {
          "type": "integer"
        },
        "time_in_seconds": {
          "type": "float"
        }
      }
    }
  }
}

Parameters for numeric fields

edit

The following parameters are accepted by numeric types:

`coerce`	Try to convert strings to numbers and truncate fractions for integers. Accepts `true` (default) and `false`.
`boost`	Field-level index time boosting. Accepts a floating point number, defaults to `1.0`.
`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`.
`ignore_malformed`	If `true`, malformed numbers are ignored. If `false` (default), malformed numbers throw an exception and reject the whole document.
`include_in_all`	Whether or not the field value should be included in the `_all` field? Accepts `true` or `false`. Defaults to `false` if `index` is set to `no`, or if a parent `object` field sets `include_in_all` to `false`. Otherwise defaults to `true`.
`index`	Should the field be searchable? Accepts `not_analyzed` (default) and `no`.
`null_value`	Accepts a numeric value of the same `type` as the field which is substituted for any explicit `null` values. Defaults to `null`, which means the field is treated as missing.
`precision_step`	Controls the number of extra terms that are indexed to make `range` queries faster. The default depends on the numeric `type`.
`store`	Whether the field value should be stored and retrievable separately from the `_source` field. Accepts `true` or `false` (default).
