I have Janusgraph with Scylla and Elasticsearch as a backend. I created a schema using management API and one of the properties had a defintion like this

janusGraphManagement.addIndexKey(graphIndex, propertyKey, Mapping.TEXT.asParameter());

After ingesting all the data I realized that we need a keyword search as well, so I would like to modify the definition and reindex, and os if I created it from scratch it would be like this

But I did not find any recipe of how to do that. Could you please advise?
