Searching uncategorised models.

For the life of me, I cannot find a way to search for models which have no main category (not in character, style etc, for example https://civitai.com/models/95973/abstract-photo). Going through All is highly impractical. Is there any workaround / extension to find them?

You could manually create the URL. For example if you want to search the "abstract" category, you can type: https://civitai.com/tag/abstract
It's not an ideal solution, but it beats going through every model.
