Stricter checking for wildcard queries on _indexedit
Previously, a wildcard query on the _index
field matched directly against the
fully-qualified index name. Now, in order to match against remote indices like
cluster:index
, the query must contain a colon, as in cl*ster:inde*
. This
behavior aligns with the way indices are matched in the search endpoint.
