Can I vibe code SearchNode?

Build a high-performance ecommerce hybrid search service using Node.js, Typesense, and OpenAI vector embeddings.

1. DATA MODEL:
- Product document schema: id (string), title (string), description (text), sku (string), brand (string), categories (string array), price (float), compare_at_price (float), inventory_count (integer), created_at (timestamp), embedding (float array), attributes (object for dynamic facets like color/size), sales_30d (integer).
- Merchandising rules table: rule_id, query_pattern (string/regex), pinned_product_ids (string array), boosted_attribute_rules (array of objects with attribute, value, factor), hidden_product_ids (string array).
- Analytics event store: session_id, query, clicked_product_id, converted (boolean), timestamp.

2. CORE FUNCTIONALITY:
- Catalog Sync Pipeline: HTTP webhook endpoint accepting product creation, modification, and deletion events from the platform. Generate embeddings for updated text (title + description + brand) via OpenAI text-embedding-3-small and upsert to Typesense.
- Hybrid Search Endpoint (/api/search): Accepts query string, facet filters, sort order, page, and limit. Query Typesense using hybrid search combining keyword match score with vector distance using Reciprocal Rank Fusion (RRF).
- Merchandising Pipeline: Prior to returning search results, evaluate query against Merchandising Rules table. Inject pinned products into position, apply numeric attribute boosts, and strip hidden IDs from output payload.
- Autocomplete Endpoint (/api/autocomplete): Light-weight endpoint execution returning matching query suggestions, top 3 category matches, and top 4 product preview cards in under 30ms.

3. FAILURE MODES & EDGE CASES:
- Zero Results Fallback: If hybrid query returns zero or fewer than 3 items, strip dynamic filters and fallback to pure semantic vector search, returning payload marked with flag 'is_fallback: true'.
- Cache Strategy: Implement Redis caching for the top 200 common queries with a 15-minute TTL, invalidating when catalog sync runs.

4. OUT OF SCOPE:
- Drag-and-drop dashboard UI for merchandising (use API or DB edits).
- Real-time personal account demographic profiling.
