Hi,
is ILM need multiple index with date or single index ?
example index tes-2019-07-02 or tes.

an ILM policy can be configured at any index, but this mostly makes sense when you something like time based indices - indices, which change over time (in size, in number of documents, older data gets less queried, etc).
Can you elaborate about the use-case you are pursuing?

Yes, the idea is that you move data between nodes of different capacity when you change between hot/warm/cold. And you cannot do that on a single node.
