#### Issue: Large bulk imports timing out

**Solution**:
- Split large files into smaller batches (e.g., 10,000 docs per file)
- Increase timeout in `system.properties`:
  ```properties
  crawler.document.request.timeout=600000
  ```
- Use asynchronous import via Admin UI instead of API

#### Issue: Special characters in documents not displaying correctly

**Solution**:

        final long createdTime = ((Number) body.get("createdTime")).longValue();
        final long expiredTime = ((Number) body.get("expiredTime")).longValue();
        // event TTL = 600000
        assertEquals(600000L, expiredTime - createdTime);
    }
