# ES|QL MV_SLICE function
## Syntax

![Embedded](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/query-languages/esql/images/functions/mv_slice.svg)


## Parameters

<definitions>
  <definition term="field">
    Expression that can be null, a single value, or multiple values. If `null`, the function returns `null`.
  </definition>
  <definition term="start">
    Start position. If `null`, the function returns `null`. The start argument can be negative. An index of -1 is used to specify the last value in the list.
  </definition>
  <definition term="end">
    End position(included). Optional; if omitted, the position at `start` is returned. The end argument can be negative. An index of -1 is used to specify the last value in the list.
  </definition>
</definitions>


## Description

Returns a subset of the multivalued field using the start and end index values. Indexes are 0-based. This is most useful when reading from a function that emits multivalued columns in a known order like [`SPLIT`](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/query-languages/esql/functions-operators/string-functions/split) or [`MV_SORT`](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/query-languages/esql/functions-operators/mv-functions/mv_sort).
The order that [multivalued fields](https://www.elastic.co/elastic/docs-builder/docs/3028/reference/query-languages/esql/esql-multivalued-fields) are read from
underlying storage is not guaranteed. It is **frequently** ascending, but don’t
rely on that.

## Examples

```esql
row a = [1, 2, 2, 3]
| eval a1 = mv_slice(a, 1), a2 = mv_slice(a, 2, 3)
```


| a:integer    | a1:integer | a2:integer |
|--------------|------------|------------|
| [1, 2, 2, 3] | 2          | [2, 3]     |

```esql
row a = [1, 2, 2, 3]
| eval a1 = mv_slice(a, -2), a2 = mv_slice(a, -3, -1)
```


| a:integer    | a1:integer | a2:integer |
