You can resubmit for indexing all documents that failed indexing. This menu choice executes the mark_for_retry administration method. If the indexing system is installed in a high-availability configuration, all failed queue items for all indexes are resubmitted.
To resubmit all objects that failed indexing:
Connect to the repository as user who has system administrator or superuser privileges.
Navigate to Administration > Indexing Management > Index Queue.
Select Tools > Resubmit all failed queue items.
