Subject: [PATCH] Update the backend API to include new isIndexed methods that can be used to determine whether a given attribute is indexed in a specified manner, or that can be used to determine whether a specified filter is indexed. At present, all backends except the JE backend and the replication backend are considered always indexed for all operations. The JE backend is only considered indexed based on its index configuration. The replication backend is never considered indexed.
