filter

The Filter is used to identify objects that a Lifecycle Rule applies to. A Filter must have exactly one of Prefix, Tag, ObjectSizeGreaterThan, ObjectSizeLessThan, or And specified. Filter is required if the LifecycleRule does not contain a Prefix element.

For more information about Tag filters, see Adding filters to Lifecycle rules in the Amazon S3 User Guide.

Tag filters are not supported for directory buckets.
