I have an index with a string field named "Hostname". And there is also an automatically created HostName.Keyword field.
I use this -keyword-field for aggregations, e.g. in an Control-Visualisation.
Problem now is that the values of this keyword fields are not updated with new values in new documents.
At the beginning (Index cretation, Indexpatter createion) only two hostnames existed. Now a third one exists in the documents. How do I make the new value available in the keyword field?
