+# Park Search Implementation Improvements
+
+## Context
+The park search functionality needed to be updated to follow consistent patterns across the application and strictly adhere to the "NO CUSTOM JS" rule. Previously, search functionality was inconsistent and did not fully utilize built-in framework features.
+
+## Decision
+Implemented a unified search pattern that:
+1. Uses only built-in HTMX and Alpine.js features
+2. Matches location search pattern
+3. Removes any custom JavaScript files
+4. Maintains consistency across the application
+
+### Benefits
+1. **Simplified Architecture:**
+   - No custom JavaScript files needed
+   - Direct template-based implementation
+   - Reduced maintenance burden
+   - Smaller codebase
+
+2. **Framework Alignment:**
+   - Uses HTMX for AJAX requests
+   - Uses Alpine.js for state management
+   - All functionality in templates
+   - Follows project patterns
+
+3. **Better Maintainability:**
+   - Single source of truth in templates
+   - Reduced complexity
+   - Easier to understand
+   - Consistent with other features
+
+## Implementation Details
+
+### Template Features
+1. HTMX Integration:
+   - Debounced search requests (300ms)
+   - Loading indicators
+   - JSON response handling
+
+2. Alpine.js Usage:
+   - State management in template
+   - Event handling
+   - UI updates
+   - Keyboard interactions
+
+### Backend Changes
+1. JSON API:
+   - Consistent response format
+   - Type validation
+   - Limited results (8 items)
+   - Performance optimization
+
+2. View Updates:
+   - Search filtering
+   - Result formatting
+   - Error handling
+   - State preservation
+
+## Benefits
+1. Better adherence to project standards
+2. Simplified codebase
+3. Reduced technical debt
+4. Easier maintenance
+5. Consistent user experience
+
+## Testing
+1. API response format
+2. Empty search handling
+3. Field validation
+4. UI interactions
+5. State management

+# Search Form Fix
+
+## Issue
+Search results were being duplicated because selecting a suggestion triggered both:
+1. The suggestions form submission (to /suggest_parks/)
+2. The filter form submission (to /park_list/)
+
+## Root Cause
+The `@search-selected` event handler was submitting the wrong form. It was submitting the suggestions form which has `hx-target="#search-results"` instead of the filter form which has `hx-target="#park-results"`.
+
+## Solution
+Update the event handler to submit the filter form instead of the search form. This ensures only one request is made to update the results.
+
+## Implementation
+1. Modified the `@search-selected` handler to:
+   - Set the search query in filter form
+   - Submit filter form to update results
+   - Hide suggestions dropdown
+2. Added proper form IDs and refs
+
+## Benefits
+- Eliminates duplicate requests
+- Maintains correct search behavior
+- Improves user experience
