To troubleshoot why your search is down and get it back up as fast as possible, we recommend the following steps.
1) Log in to your application via the dashboard. Are your results loading? If so, the issue is likely unrelated to your data in Algolia. It may be a configuration or front end issue.
2) Go to your search page and look at the network request you get back using the inspector of your browser. Do you see an error message or are you getting hits back?
a) If you are getting an error message, the message should tell you the cause of the issue
b) If you are getting hits back, the issue is related to your front end.
