+# Park Search Implementation
+
+## Overview
+Integration of the parks app with the site-wide search system, providing both full search functionality and quick search for dropdowns.
+
+## Components
+
+### 1. Filter Configuration (parks/filters.py)
+```python
+ParkFilter = create_model_filter(
+    model=Park,
+    search_fields=['name', 'description', 'location__city', 'location__state', 'location__country'],
+    mixins=[LocationFilterMixin, RatingFilterMixin, DateRangeFilterMixin],
+    additional_filters={
+        'status': {
+            'field_class': 'django_filters.ChoiceFilter',
+            'field_kwargs': {
+                'choices': Park._meta.get_field('status').choices,
+                'empty_label': 'Any status',
+                'null_label': 'Unknown'
+            }
+        },
+        'opening_date': {
+            'field_class': 'django_filters.DateFromToRangeFilter',
+            'field_kwargs': {
+                'label': 'Opening date range',
+                'help_text': 'Enter dates in YYYY-MM-DD format'
+            }
+        },
+        # Additional filters for rides, size, etc.
+    }
+)
+```
+
+### 2. View Implementation (parks/views.py)
+
+#### Full Search (ParkListView)
+```python
+class ParkListView(HTMXFilterableMixin, ListView):
+    model = Park
+    filter_class = ParkFilter
+    paginate_by = 20
+
+    def get_queryset(self):
+        try:
+            return (
+                super()
+                .get_queryset()
+                .select_related("owner")
+                .prefetch_related(
+                    "photos",
+                    "location",
+                    "rides",
+                    "rides__manufacturer"
+                )
+                .annotate(
+                    total_rides=Count("rides"),
+                    total_coasters=Count("rides", filter=Q(rides__category="RC")),
+                )
+            )
+        except Exception as e:
+            messages.error(self.request, f"Error loading parks: {str(e)}")
+            return Park.objects.none()
+```
+
+#### Quick Search
+```python
+def search_parks(request):
+    try:
+        queryset = (
+            Park.objects.prefetch_related('location', 'photos')
+            .order_by('name')
+        )
+        filter_params = {'search': request.GET.get('q', '').strip()}
+        park_filter = ParkFilter(filter_params, queryset=queryset)
+        parks = park_filter.qs[:10]
+        
+        return render(request, "parks/partials/park_search_results.html", {
+            "parks": parks,
+            "is_quick_search": True
+        })
+    except Exception as e:
+        return render(..., {"error": str(e)})
+```
+
+### 3. Template Structure
+
+#### Main Search Page (parks/templates/parks/park_list.html)
+- Extends: search/layouts/filtered_list.html
+- Blocks:
+  * filter_errors: Validation error display
+  * list_header: Park list header + actions
+  * filter_section: Filter form with clear option
+  * results_section: Park results with pagination
+
+#### Results Display (search/templates/search/partials/park_results.html)
+- Full park information
+- Status indicators
+- Ride statistics
+- Location details
+- Error state handling
+
+#### Quick Search Results (parks/partials/park_search_results.html)
+- Simplified park display
+- Basic location info
+- Fallback for missing images
+- Error handling
+
+### 4. Error Handling
+
+#### View Level
+- Try/except blocks around queryset operations
+- Filter validation errors captured
+- Generic error states handled
+- User-friendly error messages
+
+#### Template Level
+- Error states in both quick and full search
+- Safe data access (using with and conditionals)
+- Fallback content for missing data
+- Clear error messaging
+
+### 5. Query Optimization
+
+#### Full Search
+- select_related: owner
+- prefetch_related: photos, location, rides, rides__manufacturer
+- Proper annotations for counts
+- Pagination for large results
+
+#### Quick Search
+- Limited to 10 results
+- Minimal related data loading
+- Basic ordering optimization
+
+### 6. Known Limitations
+
+1. Testing Coverage
+   - Need unit tests for filters
+   - Need integration tests for error cases
+   - Need performance testing
+
+2. Performance
+   - Large dataset behavior unknown
+   - Complex filter combinations untested
+
+3. Security
+   - SQL injection prevention needs review
+   - Permission checks need audit
+
+4. Accessibility
+   - ARIA labels needed
+   - Color contrast validation needed
+
+### 7. Next Steps
+
+1. Testing
+   - Implement comprehensive test suite
+   - Add performance benchmarks
+   - Test edge cases
+
+2. Monitoring
+   - Add error logging
+   - Implement performance tracking
+   - Add usage analytics
+
+3. Optimization
+   - Profile query performance
+   - Optimize filter combinations
+   - Consider caching strategies
