=== Time-based internal index patterns queried as wildcard index patterns
*Details:* Time-based interval index patterns were deprecated in 5.x. In 6.x,
you could no longer create time-based interval index patterns, but they continued
to function as expected. In 7.2, functionality has changed such that {kib} will
automatically query a time-based interval index pattern as a wildcard index pattern.
Support for time-based index patterns will be removed in 8.0. You can migrate your
time-based index patterns to a wildcard pattern to prepare for this change.
*Impact:* If you query a time-based index pattern, that query will now be performed
on the root wildcard term. For example, a query on an index pattern such as
`[logstash-]YYYY.MM.DD` will now query all indices that match `logstash-*`.
