在每个文档中查找数组类型字段的长度(大小) [英] Find length (size) of the array type field in each doc

问题描述

我的索引中有一个字段，它是一个整数数组.我要添加另一个包含元素数量计数的字段.

I have a field in my index which is an integer array. I want to add another field which contains the count of the number of elements.

即使提供计数的API调用也没问题.

Even an API call that gives the count is fine.

我发现了一些相关的东西:"script":"doc ['MyField'].values.size()"

I have found something relevant : "script" : "doc['MyField'].values.size()"

但是我不知道&在哪里使用它.请帮忙！

But I don't know how & where to use it. Please help!
