anyone using Low Search Module for advanced search?

I am not sure if this is a low search module question or if it would be part of the native EE search module. So i am putting it out there! 😊

I have an advanced search (not incredibly advanced) and non-members cannot use the search. If you are a member the search works and returns results, if you are a non-member there is an error: You are not authorized to perform this action.

I feel like I have gone through every setting for each module, member, global preferences etc. But can’t seem to determine why the search wouldn’t work for non-members.

Any ideas?
