Can you elaborate a little more on what you mean by that?

No, you will need to run a [delete by query](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html) for that.

You can always change your patterns;

- `customer-lpb` - note, no `*`
- `customer-lpb-*` - to cater for the monthly indices

Also, you should really use dates rather than month names, eg `customer-lpb-2020-02`, not `customer-lpb-feb`.
