Scheduled indexing is used to fully rebuild an index automatically and regularly.
Scheduled rebuilding is recommended for all
Production instances, even if incremental indexing is enabled. This prevents index
fragmentation. Scheduled indexing is available on Staging, Production, and Development
instances. Scheduled indexing features are not available for Cloudboxes or Sandboxes, because
these instance types don't execute scheduled processes.
Note: It is recommended that you turn
off scheduled indexing during data replication.
