# Sort Modes

|
## 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
|
