Can I vibe code AddSearch?

Build a self-hosted instant site search system to replace AddSearch using Node.js, Typesense, and standard frontend JavaScript.

1. ARCHITECTURE & DATA MODEL
- Deploy a Typesense instance (or local Docker container for development).
- Define a Typesense schema for `documents`: `id` (string), `url` (string, primary key), `title` (string), `content` (string), `category` (string, facet), `image_url` (string), `price` (float, optional facet), `updated_at` (int64).
- Build a Node.js indexing service with two input channels: Webhook API endpoints for real-time CRUD and a Sitemap Crawler.

2. SITEMAP CRAWLER & INDEXER
- Parse an XML sitemap URL provided in environment variables.
- Fetch each URL using `axios` and parse HTML with `cheerio`.
- Extract metadata: `og:title`, canonical URL, `og:image`, main body text (excluding nav, footer, scripts), and page category.
- Batch upsert extracted document objects into the Typesense `documents` collection using `client.collections('documents').documents().import(docs, {action: 'upsert'})`.
- Include basic rate limiting (max 5 concurrent requests) to avoid server bans.

3. FRONTEND SEARCH WIDGET
- Create a lightweight vanilla JS drop-in library (`search-widget.js`) exposed via a global namespace.
- Render an overlay search modal triggered by an input field or shortcut (e.g. Cmd+K).
- Execute search queries against the Typesense REST API using debounce (200ms).
- Display instant search results with highlighted matching text snippet, title, thumbnail image, and price/category badges.
- Support keyboard navigation (Arrow Up, Arrow Down, Enter, Escape).

4. ANALYTICS TELEMETRY
- Log query events to an internal PostgreSQL table `search_logs`: `query` (string), `result_count` (int), `clicked_url` (string, optional), `timestamp` (datetime).
- Create a simple REST API endpoint `/api/analytics/top-searches` and `/api/analytics/zero-results` to track missed customer queries.

5. OUT OF SCOPE
- Complex vector-based semantic search or LLM embeddings.
- Document parsing for PDF/Docx files.
- Visual drag-and-drop merchandising rule editors.
