Hello, thank you for pointing me to the right methods.
I tried to use the reindex.
But if I try to use my index as source and dest, I get an error.
How can I reindex the CSV again?
I mean, how do I add it to the source of the _reindex ?
Sorry if I missed something in the docs but I cans find how to set a CSV as source.
I used Kibana Machine Learning File import to do the first import
Ah, maybe I have to import the file in a index without changing anything first like myFile_native and then do a reindex into a new one like myFile_foruse with my changes and use the myFile_foruse in the application right?
