+## Search Architecture
+
+### Search Infrastructure
+- **Base Pattern**: [`BaseAutocomplete`](core/forms.py:1) provides authentication-first autocomplete foundation
+- **Park Search**: [`ParkAutocomplete`](search/mixins.py:1) + [`ParkSearchForm`](search/forms.py:1) with HTMX integration
+- **Ride Search**: Planned extension following same pattern with park relationship context
+
+### Search Components
+1. **Autocomplete Layer**
+   - Authentication requirement enforced at base level
+   - Query limiting (10 results) for performance
+   - HTMX-driven real-time suggestions
+
+2. **Form Layer**
+   - Django forms with autocomplete widgets
+   - Filter integration for advanced search
+   - Clean validation and error handling
+
+3. **Frontend Integration**
+   - HTMX for dynamic updates (`hx-get`, `hx-trigger`)
+   - AlpineJS for local state management
+   - Tailwind CSS for consistent styling
+
+### Database Optimization
+- Indexes on searchable fields (`name`, foreign keys)
+- `select_related()` for relationship queries
+- Query result limiting for performance
+
 ## Integration Points
 
 1. **External Services**
