I think the classification engine is likely just like 500 common object classifications. It's quite old and has been around for ages so I don't think it is currently as sophisticated as modern LLMs etc. So "sand" and "face" are probably fine, but "sand on face" might be tricky. No idea though - just guessing from my own personal experience

It was also hobbled quite hard near the start as they had a scare with searches for "gorilla" accidentally returning pictures of black people so they have probably turned all the safety knobs they have up to 11, even if that impacts recall.
