# Park Search Implementation

## Search Flow

1. **Quick Search (Suggestions)**
   - Endpoint: `suggest_parks/`
   - Shows up to 8 suggestions
   - Uses HTMX for real-time updates
   - 300ms debounce for typing

2. **Full Search**
   - Endpoint: `parks:park_list`
   - Shows all matching results
   - Supports view modes (grid/list)
   - Integrates with filter system

## Implementation Details

### Frontend Components
- Search input using built-in HTMX and Alpine.js
  ```html
  <div x-data="{ query: '', selectedId: null }"
       @search-selected.window="...">
    <form hx-get="..." hx-trigger="input changed delay:300ms">
      <!-- Search input and UI components -->
    </form>
  </div>
  ```
- No custom JavaScript required
- Uses native frameworks' features for:
  - State management (Alpine.js)
  - AJAX requests (HTMX)
  - Loading indicators
  - Keyboard interactions

### Templates
- `park_list.html`: Main search interface
- `park_suggestions.html`: Partial for search suggestions
- `park_list_item.html`: Results display

### Key Features
- Real-time suggestions
- Keyboard navigation (ESC to clear)
- ARIA attributes for accessibility
- Dark mode support
- CSRF protection
- Loading states

### Search Flow
1. User types in search box
2. After 300ms debounce, HTMX sends request
3. Server returns suggestion list
4. User selects item
5. Form submits to main list view with filter
6. Results update while maintaining view mode

## Recent Updates (2024-02-22)
1. Fixed search page loading issue:
   - Removed legacy redirect in suggest_parks
   - Updated search form to use HTMX properly
   - Added Alpine.js for state management
   - Improved suggestions UI
   - Maintained view mode during search

2. Security:
   - CSRF protection on all forms
   - Input sanitization
   - Proper parameter handling

3. Performance:
   - 300ms debounce on typing
   - Limit suggestions to 8 items
   - Efficient query optimization

4. Accessibility:
    - ARIA labels and roles
    - Keyboard navigation
    - Proper focus management
    - Screen reader support
