Hi @pytomtoto ,

Probably this is a feature request for Index Management plugin.
In their user guide (https://opensearch.org/docs/latest/im-plugin/ism/policies/), it's not mentioned that "index_patterns" supports excluding targets with the syntax -.
I will ask the team to transfer the issue to index-managment repository to let the developers there give a better answer.

ISM doesn't support - pattern to exclude sth. This can be a feature request.

Should be a very useful feature
