Hey,

so this requires the explanation about the difference between ingest processors and analysis. The short variant is

  • An ingest processor is able modify the JSON document
  • An analysis step (character filter/token filter) is able to modify the data the gets stored in the inverted index

This means, if you retrieve the document via the Get API, the first will show modified JSON in the _source, where as the second, will show the document as you indexed it.

Hope this helps as a start.
