Yeah, traditional Boolean search would be an improvement in some ways: “show me men taller than 6, or programmers of any height” (heh), but that’s either too overwhelming for users, or promotes spam or scraping or stalking or something. But maybe more choice isn’t the answer. Or maybe if you gave people the flexibility, they would be more cognizant of all the things they’re missing out on, and of the difficulty of getting it right, and take a less targeted approach with less “overfitting”. But the current system of independent “AND” cutoffs is what people get forced into. And an algorithm is a good alternative, but people don’t trust the algorithms much.
