Hi
for using the update query i referred to
[http://www.elasticsearch.org/guide/reference/api/update/](http://www.elasticsearch.org/guide/reference/api/update/)
eg: And, we can delete the doc if the tags contain blue, or ignore (noop):
curl -XPOST 'localhost:9200/test/type1/1/\_update' -d '{
"script" : "ctx.\_source.tags.contains(tag) ? ctx.op = "delete" : ctx.op
= "none"",
"params" : {
"tag" : "blue"
}
}'
I have modified the above query as follows:
curl -XPOST "[http://10.118.192.145:9200/test/type1/1/\_update](http://10.118.192.145:9200/test/type1/1/_update)" -d '{
"script" : "ctx.\_source.tags.contains(tag) ? ctx.op = "none" : ctx.\_source.tags += tag",
"params" : {
"tag" : "Orange"
}
}'
I want to check for a tag before adding to it. If the tag exists, do nothing else perform the update to add.
the above query creates a new version for the record but does not add the new tag.
How can i acheive this?
Thanks
Kuwar Sahani

Hey,
this works
curl -XPUT localhost:9200/test/type1/1 -d '{
"counter" : 1,
"tags" : ["red"]
}'
curl -XPOST 'localhost:9200/test/type1/1/\_update' -d '{
"script" : "!ctx.\_source.tags.contains(tag) ? ctx.\_source.tags += tag :
ctx.op = "none"",
"params" : {
"tag" : "blue"
}
}'
curl localhost:9200/test/type1/1
this does not
curl -XPUT localhost:9200/test/type1/1 -d '{
"counter" : 1,
"tags" : ["red"]
}'
curl -XPOST 'localhost:9200/test/type1/1/\_update' -d '{
"script" : "ctx.\_source.tags.contains(tag) ? ctx.op = "none" :
ctx.\_source.tags += tag ",
"params" : {
"tag" : "blue"
}
}'
curl localhost:9200/test/type1/1
looks like a bug, I need to check that further, in the meantime try the
first solution...
