Special characters in field names

Elastic Stack Elasticsearch

Is there any restriction in using some characters in field names ?

Are these names valid ?

  • "field.name"
    -"#fieldname"
  • "@field.name"
  • "-field.name"

Thanks !

I would avoid using embedded '.' as that is used to step into objects,
eg { foo: { bar: 1}} could access bar using 'foo.bar'

Also, avoid starting a field name with _

other than that, i think the other characters are legal

I add that I would avoid + and - as you can use it in query string query as a must or must not clause.
