I want to start a project and we will use es as search engine!! I have a few questions. I know how important the mapping is. I have read some topics that if I change a field type in the mapping then the index must be deleted and created again. I want to be sure about all the cases that I describe bellow in the newest version of es. The cases are:
- Updating an existing mapping adding a new field
- Delete a field from a mapping
- Change a type of a field in the mapping
In which cases my Index must deleted and recreated? Thank you a lot for your answers!!
