+# 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
