Converts a multivalued field into a single valued field containing the minimum value. For example:
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/math.csv-spec[tag=mv_min]
|
|
----
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
|
|===
|
|
include::{esql-specs}/math.csv-spec[tag=mv_min-result]
|
|
|===
|
|
|
|
It can be used by any field type, including `keyword` fields. In that case picks the
|
|
first string, comparing their utf-8 representation byte by byte:
|
|
|
|
[source.merge.styled,esql]
|
|
----
|
|
include::{esql-specs}/string.csv-spec[tag=mv_min]
|
