The different <<fe_kind,`kinds`>> are described as follows:
=== prefix
To match all indices starting with `logstash-`:
[source,yaml]
-------------
- filtertype: pattern
kind: prefix
value: logstash-
-------------
To match all indices _except_ those starting with `logstash-`:
[source,yaml]
-------------
- filtertype: pattern
kind: prefix
value: logstash-
exclude: True
-------------
NOTE: Internally, the `prefix` value is used to create a _regex_ pattern: `^{0}.*$`. Any special
characters should be escaped with a backslash to match literally.
=== suffix
To match all indices ending with `-prod`:
[source,yaml]
-------------
- filtertype: pattern
kind: suffix
value: -prod
-------------
To match all indices _except_ those ending with `-prod`:
[source,yaml]
-------------
- filtertype: pattern
kind: suffix
value: -prod
exclude: True
-------------
NOTE: Internally, the `suffix` value is used to create a _regex_ pattern: `^.*{0}$`. Any special
characters should be escaped with a backslash to match literally.
=== timestring
IMPORTANT: No age calculation takes place here. It is strictly a pattern match.
To match all indices with a Year.month.day pattern, like `index-2017.04.01`:
[source,yaml]
-------------
- filtertype: pattern
kind: timestring
value: '%Y.%m.%d'
-------------
To match all indices _except_ those with a Year.month.day pattern, like
`index-2017.04.01`:
[source,yaml]
-------------
- filtertype: pattern
kind: timestring
value: '%Y.%m.%d'
exclude: True
-------------
include::inc_timestring_regex.asciidoc[]
=== regex
This <<fe_kind,`kind`>> allows you to design a regular-expression to match
indices or snapshots:
To match all indices starting with `a-`, `b-`, or `c-`:
[source,yaml]
-------------
- filtertype: pattern
kind: regex
value: '^a-|^b-|^c-'
-------------
To match all indices _except_ those starting with `a-`, `b-`, or `c-`:
[source,yaml]
-------------
- filtertype: pattern
kind: regex
value: '^a-|^b-|^c-'
exclude: True
-------------
