elasticsearch curator delete "all" indices order than 7 days - elasticsearch

Question

background:
elasticsearch version 6.2
curator version 5.4.1.
Now I can use curator to delete one index that order 7 days, but I have more than one index and I don't want to create more than one action.yml, such as :
actions:
1:
action: delete_indices
description: >-
Delete indices older than 7 days (based on index name), for student-prefixed indices. Ignore the error if the filter does not result in an actionable list of indices (ignore_empty_list) and exit cleanly.
options:
ignore_empty_list: True
disable_action: False
filters:
- filtertype: pattern
kind: prefix
value: student=
- filtertype: age
source: name
direction: older
timestring: '%Y-%m-%d'
unit: days
unit_count: 7
According to this action.yml, It deletes student=2017-XX-XX.
But I have many indices such as teacher, parent and so on.
I replace studnet= with *= but doesn't work.
So what can I do?
Thank you very much.

You try a few things. A few examples include:
You can omit the pattern filtertype, leaving only the age. This might delete other indices with %Y-%m-%d patterns, however. In that case, you might use a different pattern filter, but to exclude patterns you don't want to delete:
- filtertype: pattern
kind: prefix
value: omit_me
exclude: true
Replacing your pattern filter with this will delete all indices with %Y-%m-%d that are older than 7 days, except indices starting with omit_me.
You might set up a regex instead of a prefix. For example:
- filtertype: pattern
kind: regex
value: '^(student|parent|teacher).*$'
This will match indices starting with student, parent, or teacher.
