The root cause of this exception is corruption while reading Lucene index – the exception roots from Lucene.

The precise reason behind the corrupted index cannot be determined by the error message. Some times it is reported due to a conflict in Lucene/Java jars, other times due to corrupt disk segment/RAM etc.

Note: This corruption is in Concept search specific Lucene Index only, and should not affect other areas of the product.

Since the cause of the exception seen in Search Analytics log is not determined it is recommended to turn off Concept Search.

Please follow the steps below:

1. Select the affected case from 'All Cases', and click on Settings.
2. Under 'Configure processing parameters and features', uncheck 'Enable concept search' and click on Save button at the bottom
3. Please see the screen shot:
