Degrade Search Index - SharePoint 2013

    Question

  • Dear All,

    In one of our customer environment, we are facing some strange issue where the index component is degrading multiple times. Once it is deducted as degraded (showing exclamation mark - warning),  we have performed the index reset and run the full crawl. Full crawl completed successfully, but later we found that the incremental crawl which is scheduled to run every one day, took a long duration. Then we found the index is degarding and later online. This is happening many times. Customer also restarted the entire sharepoint farm and still the same issue. The index location has almost 60 GB free space.

    Please help to resolve on this. Thanks!

  • Hi,

    This is a long shot, but I encountered a case where the antivirus on the local server was interfering with the SharePoint setup files. All SharePoint directories have to be excluded from antivirus scans.

  • Hi IRS,

    I am checking to see how things are going there on this issue.

    Thanks,

  • Yes, the exclusion is done for all the SharePoint directories. Any other thoughts to resolve this please?

    But the index is online for few minutes and then it becomes offline. Again it came back online which is really strange to judge.
