# Sprint 10 - Advanced Search & Catalog Report
## 1. Architecture
- Existing platform architecture was preserved.
- No authentication flow changes.
- No payment flow changes.
- No bootstrap loading flow changes.
- Widget engine and section engine were not modified.
- ProductFacade was only extended (no contract removals or breaking changes).
### Data Flow
- Catalog UI calls ProductFacade only.
- ProductFacade extensions for sprint 10:
- search(criteria)
- filter(criteria)
- sort(criteria)
- loadCatalog(criteria)
- No HttpClient usage in feature layer.
## 2. New Reusable Components
### Search Module
- CatalogSearchBoxComponent
- keyword search
- instant suggestions (frontend-prepared, backend-ready)
- recent searches
- search history
- loading and no-results hint
### Filters Module
- CatalogFiltersPanelComponent
- dynamic filter rendering from filter definitions
- supports multi-select, range, toggle filter types
### Sorting Module
- CatalogSortingControlComponent
- configurable sort options
### Layout Module
- CatalogLayoutSwitcherComponent
- grid
- large grid
- compact grid
- list
### Search Results Module
- CatalogSearchResultsComponent
- loading skeletons
- summary
- pagination
- empty state
### Product Card Enhancements
- Added placeholders (no business logic):
- favorite
- compare
- quick view
- Added stock badge and configurable discount/rating/availability visibility.
## 3. Domain Models
Added reusable catalog/search models:
- SearchCriteria
- FilterDefinition
- FilterOption
- SortDefinition
- CatalogView
- SearchResult
File:
- src/app/core/products/models/catalog-experience.model.ts
## 4. Bootstrap Additions
Added catalog feature configuration (config only, no catalog data):
- layout
- navigationMode
- defaultSort
- availableSorts
- enabledFilters
- showBreadcrumbs
- showCategoryBanner
- showSubcategoryChips
- showRatings
- showDiscounts
- showAvailability
- suggestionsEnabled
- searchHistoryEnabled
Files:
- src/app/shared/models/config/catalog-config.model.ts
- src/app/shared/models/config/bootstrap-config.model.ts
- src/assets/mock/bootstrap/bootstrap.json
## 5. Backend Expectations
Documented current and future-ready expectations:
- Current:
- GET /searchitems
- GET /category/{id}
- Future-ready:
- GET /search/suggestions?q={term}
- GET /catalog/filters?category={id}&q={term}
## 6. Validation Results
### Build
- npm run build: PASS
### Architecture
- npm run arch:check:boundaries: PASS
- npm run arch:check:cycles: PASS
### Layering checks
- HttpClient in feature layer: none found
- DTO leaks in feature layer: none found (search matched addToCart text only, not DTO usage)
### Compatibility
- Widget compatibility preserved
- Section engine compatibility preserved
## 7. Documentation Updated
- docs/platform/00-bootstrap-example.md
- docs/platform/02-bootstrap-json-spec.md
- docs/platform/06-api-contracts.md
- docs/platform/08-catalog-domain.md
- docs/platform/13-backend-requirements.md
- docs/backend-platform/business-apis.md
## 8. Future Extension Points
- Backend-driven suggestions endpoint integration.
- Backend-driven dynamic filter metadata (option counts/ranges/facets).
- Navigation mode implementations:
- left category navigation
- mega category layout
- top category carousel
- URL-state sync for all search/filter/sort/layout inputs.
- Dedicated saved searches / personalized search suggestions.
