Can I vibe code SearchIQ?

Build a complete open-source site search system replacing SearchIQ using Typesense as the engine, Node.js/Express as the backend middleware, and plain JavaScript for the storefront overlay widget.

1. ARCHITECTURE & DATA MODEL:
- Deploy Typesense service with a schema for 'products' (id, title, description, vendor, product_type, price, tags, inventory_quantity, image_url, url, created_at_timestamp).
- Create a Postgres database for administration with tables: 'synonyms' (id, root_term, synonym_list), 'curated_rules' (id, query_term, pinned_product_ids, hidden_product_ids, boost_factor), and 'search_logs' (id, query, result_count, clicked_product_id, created_at).

2. CORE FUNCTIONALITY & APIS:
- Express API endpoint GET /api/search: Wraps Typesense API. Accepts 'q', 'page', 'facets', 'sort'. Applies synonym maps and checks 'curated_rules' table before sending query to Typesense to pin or override search rankings.
- Express API endpoint POST /api/analytics/log: Asynchronously logs query string, returned hit count, and click actions into Postgres without blocking response.
- Express Webhook Listener POST /api/webhooks/product-sync: Receives product creation, update, and deletion payloads from store platform and updates Typesense index instantly.
- Admin Portal (React or HTML/HTMX): UI to view top queries, zero-result queries, edit synonym lists, and visually pin products to specific queries.

3. FRONTEND OVERLAY WIDGET:
- Lightweight (~10KB) vanilla JS script injected into storefront header.
- Binds to existing search input elements (`input[type="search"]`).
- Displays styled autocomplete dropdown overlay on keyup with 150ms debounce.
- Shows product thumbnail, title, price, vendor, and highlight matching terms.

4. FAILURE MODES & RESILIENCE:
- If Typesense or search API times out (>300ms) or errors, widget must gracefully fallback to standard native platform HTML GET search form submit.
- Batch and throttle search log writes using an in-memory queue to prevent DB connection pool exhaustion during traffic spikes.

5. OUT OF SCOPE:
- Multi-lingual stemming rules, image-based visual search, and AI vector search.
