Our project contain customers. each customer doing transaction which being indexed at ES for later searching capabilities. Not all transaction structured the same and the structure is possibly to be changed (Changing fields and types/mappings). I need to design ES indexing in advanced so it will be: 1. Easy to change the doc fields(rename current ones). 2. Easy to change already existed field types. I read about aliasing mapping and re indexing but I still didn't understand the concept or how to implement this to have best practice design for my scenario, Any suggestions and farther explaining in additional to the official documentation would be warmly welcomed.
