Sort Modes
Last Updated: 2026-02-19 Confidence: High
Summary
25+ native sort modes available on any surface. The application names a sort mode; the database executes it. No application-side sorting logic required.
Key Facts:
- Sort modes are built-in, not formulas the application implements
- Same sort mode works across different candidate sets (global, category, social graph)
- Windowed top sorts: hour, today, week, month, year, all-time
- Hot uses Reddit-style age decay: score / (age + 2)^gravity
- Trending is pure velocity (rate of change), distinct from Hot (cumulative with decay)
- Controversial maximizes product of positive and negative signals
