Hello, Mr. Erick Erickson and Community Members: Thank you for your quick response.
I understand that "checkIndex -exorcise" does not actually fix the indices, more like "first aid" kinda action. And soon or later I need to re-index from my source. What is the rule of thumb to recover from the corrupted segment files?
