*Parameters*

`first`::
First of the columns to evaluate.

`rest`::
The rest of the columns to evaluate.

*Description*

Returns the minimum value from multiple columns. This is similar to
<<esql-mv_min>> except it is intended to run on multiple columns at once.

NOTE: When run on `keyword` or `text` fields, this returns the first string
      in alphabetical order. When run on `boolean` columns this will return
      `false` if any values are `false`.
