#### Issue: GSA XML import creates no configurations

**Solution**:
- Verify XML structure matches GSA export format
- Check Fess logs: `logs/fess.log`
- Look for `GsaConfigException` errors
- Ensure collections have valid URL patterns

#### Issue: Imported documents not appearing in search

**Solution**:

    // If the non-host fields of the address don't overlap, we're done.
    if (!this.route.address.equalsNonHost(address)) return false

    // If the host exactly matches, we're done: this connection can carry the address.
    if (address.url.host ==
      this
        .route()
        .address.url.host
    ) {
      return true // This connection is a perfect match.
    }

Die folgenden Argumente werden unterstützt:

* `allowed_hosts` – Eine Liste von Domain-Namen, die als Hostnamen zulässig sein sollten. Wildcard-Domains wie `*.example.com` werden unterstützt, um Subdomains zu matchen. Um jeden Hostnamen zu erlauben, verwenden Sie entweder `allowed_hosts=["*"]` oder lassen Sie diese Middleware weg.
