Hi All,

I am using groovy script to do partial updates in ElasticSearch.

I have an integer field. I want to append value to that field on each  
update request.

For example: "id" field has value 114561604. On each update request i want  
to append other id to that field as integer array like [114561604,114561605].

I am using below script:

{  
"script" : "ctx.\_source.id+=new\_tag ",  
"params" : {  
"new\_tag" : 114561605  
}  
}

For string field this script is working fine but for integer it is not  
working as expected.

Getting below error:

failed to parse [id]]; nested: NumberFormatException  
[For input string: "114561604114561605"

Please let me know how each further value can be appended as integer using  
groovy script.
