Can't search by multiple tags with Loli

The title says it all, whenever I search loli tag with any other it says nothing found, why?

Because of the controversial tag system block it. Aka bug from that preventive system.

And when it will be fixed I wonder?

Been there since the beginning. If you want you can add the tag(s) that's not incest shota loli forced or monster girl. Then use your find function on your browser to find loli or any of those tags. Could take less the 10 secs if you can click the next page quickly

Yeah, there's no chance of it getting implemented any time soon iirc.
They're hidden for a reason, and being able to search for hidden things kinda defeats the purpose

Ehm how are they hidden? I can clearly see them in Tags menu and on doujin pages themselves. Whats the point?

In your setting there's a setting called show controversial content. If it's off then those five tags will be hidden since in many countries those tags are illegal or taboo.

Its like they can't track user's country with his ip

It's illegal in pretty much every country.
It makes no sense to write something that'd potentially break, and cause them legal issues.
Better off just to leave it out, and have people search for everything else, bar the tag itself. Or just go through the loli tag, and search for what they want.

As was said, it's there for a reason, if it was that easy, it would have been done a long time ago

If they have controversial content enabled, then let them search with those terms. Seems pretty simple to me.
