### 6. Full-Text Search

```typescript
// API endpoint with PostgreSQL full-text search
export async function POST(request: Request) {
  const { query } = await request.json()
  const userId = await getUserIdFromAuth(request)

  const notes = await prisma.$queryRaw`
    SELECT
      id,
      title,
      "plainText",
      ts_rank(to_tsvector('english', title || ' ' || "plainText"), plainto_tsquery('english', ${query})) AS rank
    FROM "StudyNote"
    WHERE
      "userId" = ${userId}
      AND to_tsvector('english', title || ' ' || "plainText") @@ plainto_tsquery('english', ${query})
    ORDER BY rank DESC
    LIMIT 50
  `

  return NextResponse.json({ notes })
}
```
