As a result of a power failure or other catastrophic event, the index data may become corrupted beyond repair. In that situation, existing Index Server data is deleted and all the documents are refiltered. If corruption is detected during Index Server startup, the refiltering will happen automatically. However, if corruption is detected during normal operation, an event log message is written and no further queries are allowed. When this event is written to the event log, administrators should stop and restart the Content Index service.
When automatic recovery is performed by Index Server, an event is written to the event log. If the catalog specified in the event log message had the default settings and all the virtual roots were indexed, no action is required.
