Removing field doesn't work

Elastic Stack Elasticsearch
1

Hello,

I'm using ES 1.7
I'm trying to remove a field that only appears in some of the documents on my index. Here is my query:
curl -XPOST 'localhost:9200/data/_update' -d '{"script" : "ctx._source.remove = \"publisher\""}'

and the answer I get is:
{"error":"InvalidTypeNameException[mapping type name [_update] can't start with '_']", "status":400}

So I removed the "_" from "update":
curl -XPOST 'localhost:9200/data/update' -d '{"script" : "ctx._source.remove = \"publisher\""}'

And the output:
{"_index":"df","_type":"case", "_id":update","_varsion":1,"created":true}

But then I look at the index on kibana and it didn't delete the field.
So I tried again, the output was a bit different:
{"_index":"df","_type":"case", "_id":update","_varsion":2,"created":false}

But still didn't delete it. What am I doing wrong?

Update API in 1.7 requires a document ID. See https://www.elastic.co/guide/en/elasticsearch/reference/1.7/docs-update.html

Something like

curl -XPOST 'localhost:9200/data/type/1/_update' -d '{ ... }'

But what if I want to remove the field from ALL of the documents in that index?

Update to 2.3 would be the best option IMO.

Hi,
Thanks for the advice, but currently I can't update for a few reasons.
Do you have any other advice for me?
