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
