Hi,
I can't find a feature where I can explicitly search for public lists of other users. Even if I "like" some of the randomly shown list-suggestions, I currently can't trace them back.
My suggestion would be to create a new subcategory in the discussion forum where each user can publish their own list. It should be one post (link) for each list (*) and the title of the discussion would be the same as the title of the list. This way users can use the search function.
(*) NO collection aka all list of one user in one post as it would defy the purpose of using the search function
By the way:
There is already a suggestion about lists under the following link, but I think my suggestion differs enough and might be easy to implement:
