When you contact support to seek assistance on a Spotlight issue, you can use Spotlight tracing to include additional information in the support bundle that you send to support.
To turn on Spotlight tracing
With tracing turned on, Spotlight can collect additional information (such as the output from operating-system commands) for the rest of the current session.
When you create a support bundle with tracing turned on, the support bundle contains additional information to investigate your support issue.
Note: All tracing information gathered is from the Spotlight client. There is no server tracing capability.
