Hi All,
Need your help with rollover index.
I rollover index with conditions max\_age=1d and max\_size=50GB. The max\_age is calculated from the index creation time rather than the date field in the index name.
Is there a way to rollover based on the date\_field in the index name?

No there's not sorry. The date in the index name is based on the first run of the policy, so it doesn't change on rollover anyway.
