In the FAQ, they mention they don’t have an index, they just collect the results from other search engines.

Ok, so say they added their own website index then, how would that help with "People doesnt know where to put the content in a website or how to make accessible"?

Uh oh. Where is that? We do have our own index, Uruky Site Search!

On the settings page it appears that the index is disabled by default and not included in the ordering either. It's a bit confusing here!

It’s currently a tiny “indieweb” index, which is why it’s opt-in right now, and not big enough to be in the ordering, yet.

How do I search the index? How big is it?

I went into settings, excluded every provider, and enabled "include uruky site search", but it still says "Providers used: Mojeek", and every other search I try shows no mention of the uruky index

It’s too small right now, so we don’t allow you to search it exclusively, yet. Eventually it should become a “proper” search provider once it reaches 100M urls or so.
