Update Document

Elastic Stack Elasticsearch

Hi,

I would like to know if it is possible to update a document, for
example replace or add a field ?
I found optype = create but it seems to be the only solution.

Thanks

The default index command updates the document if it exists. optype create
just says don't check whether it exists to improve performance. So if you
want to update the doc, I think you just index it again.

Thanks, I found also this in put mapping section :
"When an existing mapping already exists under the given type, the two
mapping definitions, the one already defined, and the new ones are
merged."

If you have a field defined as 'string', then you want to change it to
'date', you can't do that. You would need to create a new mapping and
reindex all the existing documents.

I have it working as follows:

  • my app uses index 'xyz'
  • 'xyz' is an alias for 'xyz_1234'

if I want to change the mapping:

  • I create 'xyz_1235'
  • read all docs from 'xyz_1234' -> index to 'xyz_1235'
  • update alias 'xyz' to point to 'xyz_1235'
  • delete index 'xyz_1234'

Note that this are two different things, updating the mapping and updating a
document instance.
