## AI-Powered Search

We've integrated the **E5-base-v2 embedding model** to enable semantic search across your Notion graph. Now you can choose between three search modes:

- **Text Search** — classic keyword matching
- **Semantic Search** — AI understands meaning, finds conceptually related pages
- **Hybrid Search** — combines both for best results (default)

## Full-Text Content Search

Search now goes beyond page titles — it searches through **actual page content**. Results display content snippets with highlighted matches, so you can see exactly where your keywords appear.

## Similar Nodes Discovery

When you select a node, a new "Similar Nodes" panel shows pages that are **semantically related**. Great for discovering unexpected connections in your knowledge graph!

## User Authentication

Complete user system is now in place: registration, login, personal dashboard, and profile management. Your Notion workspace data is isolated with a dedicated search index.

This update brings powerful AI capabilities to your Notion knowledge graph exploration.
