Using ES 5.6.3:

I am trying to update only one entry in an array.  
For Example:  
"myArray":[  
"entry1",  
"entry2"  
]

I am trying to change the entry2 entry to entry3 and leave entry1 alone.  
If I use  
{"script": { "inline": "ctx\_source.myArray = ['entry3']", "query": {"term": {"myArray":"entry2"}}}

It sets the entire array to entry3 and removes the entry1 item from the array.

Any example I can find only addresses objects in an array where an entire field is changed.

</div>

try, `ctx._source.myArray.set(1, 'entry3')` or call `ctx._source.myArray.remove('entry2');ctx._source.myArray.add('entry3')`

Thanks for your help!

I got it to work with  
int x = ctx.\_source.myArray.indexOf('entry2');  
ctx.\_source.myArray.set(x,'entry3');
