I have the following mapping.
curl -XPUT [http://localhost:9200/cstest/](http://localhost:9200/cstest/) -d '
{
"mappings": {
"csproducts" : {
"properties" : {
"productid":{
"type" : "String"
},
"category":{
"type": "string",
"null\_value" : "N/A"
}
} //end properties
} //end csproducts
} //end mapping
}
'
Data:
curl -XPUT '[http://localhost:9200/cstest/csproducts/1](http://localhost:9200/cstest/csproducts/1)' -d '
{
"productid":"1",
"category":"software"
}'
I am updating the document with the following
curl -XPOST '[http://localhost:9200/cstest/csproducts/1](http://localhost:9200/cstest/csproducts/1)' -d'
{
"script" : "ctx.\_source.category+=new\_category",
"params" : {
"new\_category" : "development"
}
}'
I need to insert another category called "development" to the the category array.
This does not seem to be working. Any idea how to do it?

curl -XPOST '[http://localhost:9200/cstest/csproducts/1/\_update](http://localhost:9200/cstest/csproducts/1/_update)' -d'
{
"script" : "ctx.\_source.category+=new\_category",
"params" : {
"new\_category" : "development"
}
}'
Updates the data but it looks like
curl -XGET '[http://localhost:9200/cstest/csproducts/1?pretty=true](http://localhost:9200/cstest/csproducts/1?pretty=true)'
{
"\_index" : "cstest",
"\_type" : "csproducts",
"\_id" : "1",
"\_version" : 4,
"found" : true, "\_source" : {"productid":"1","productnumber":"123200","category":"softwaredevelopment"}
}
category is not saved as arrays.
