Give it a shot and disable it for a test?

Unless there's some strange software incompatibility and if the versions are same, I'm not sure why else would Opera behave differently on your machine.

I just tested it on Opera 36.0.2130.32.

It appears to be working correctly.

Is your Opera up to date?

Do you have any plugins or addons installed?

Voting this up as it seems to be a thing indeed and I can reproduce it at times.

It seems that the database is either super slow to process the request, or something else is wrong!

I'd at least suggest trying to add "NOT" tag, if nothing else. "dragon, male, -penis" to search for images not containing naughty bits, but still getting dragons!

I'd also like a list of artists that are "Currently streaming" for example! I like the idea personally. +1
