In one of our surveys, one question is an essay question. Where can I find the comments that were made for this question?
There is a 'Survey Results' tab that is on the Incident Details page - the survey results will show there.
On most systems, this tab has a 'Hidden' expression that may be keeping you from seeing it - see the image below. You may want to add 'Administrator' role to the expression if you cannot see the tab right now.
A Search as shown below will find any Incidents with returned Surveys (Using SurveyResults relationship as the trigger):
Additionally, there is Knowledge Base article #20579 which shows how to query the database and get these results (for use in a report).
In either case - the results are visible, at least under Incident.
