That's something I feel uneasy about, too. Whatever (however smart) selection
criteria, I fear, won't match my (possibly weird) preferred criteria. Sometimes
I learn by seeing "irrelevant" options, and I do care for that.

Besides, I much prefer to hone my search skill rather than being limited by
(however well-meaning) filtering. Empowerment and that.
