How can views be filtered based on ticket subject?
The Description condition only filters the text in the first comment in the ticket. This condition does not filter for ticket subject text and subsequent comment text in the ticket. This means there is not a native condition for ticket subject that can be used in views.
However, as a workaround, create a trigger to automatically tag tickets based on ticket subject data. Use the Ticket: Subject text in the trigger. You can then use the ticket tag added by the trigger to create a view for tickets with these tags. For more information, see the article: Trigger conditions and actions reference.
