I have below index :
curl -XPUT localhost:9200/test/type1/1 -d '{
"timestamp":"2015-04-15T12:00:00"
}'
I can update it and change all timestamp to another date by below command :
curl-XPOST localhost:9200/test/type1/1/\_updat -d '{
"script" :"ctx.\_source.timestamp = newts",
"params":{
"newts":"2015-03-15T08:15:00"
}
}'
But I need a way to update only some part of my time stamp for example I
want to :
new timestamp = old timestamp + 3 days
or
new timestamp = old timestamp + 1 year
any suggestion?

I found this solution :
curl -XPOST localhost:9200/test/type1/1/\_update -d '
{
,
"script" : "ctx.\_source.timestamp =
((ctx.\_source.timestamp).split(/-/)[0].toInteger()-1)+"-"+(ctx.\_source.timestamp).split(/-/)[1]
+"-"+ctx.\_source.timestamp.split(/-/)[2] ",
}'
