You can rebuild search indexes if they become corrupted or if they were accidentally deleted. Reindexing can take some time. Progress messages are displayed at the bottom of the page during reindexing. Additional details and progress messages also appear in the system console log.
You can rebuild search indexes interactively, or you can rebuild them by using a script that uses a direct connection to the database.
For more information on rebuilding search indexes interactively, see Rebuilding search indexes from the user interface.
For more information rebuilding search indexes by using a direct connection to the database, see Rebuilding search indexes by using a direct connection to the database.
