Query having firsts five elements in the array

Elastic Stack Elasticsearch
1

Hi,

Do you know any query that can be used to get first five elements in the array of the document if the array has more than 20 elements.

Basically 5 is a parameter and it can vary. please advice on this.

ex: itemID,itemlist : [ 1,2,3,4,5,6,7,8,9,10,11,12,13,14]

expected:
itemID, itemlist:[1,2,3,4,5]

Elasticsearch does not really modify the _source document. So my guess is that it would be easier to solve that on the client side.
