## Data Import Methods

Fess provides multiple methods for importing data:

### 1. Admin UI Import

**Path**: System > Backup > Upload

**Supported Formats**:
- **GSA XML** (`gsa*.xml`) - GSA configuration files

            builder.setFetchSource(fields, null);
            queryHelper.processSearchPreference(builder, userBean, docId);
            return true;
        });

    }

    /**
     * Retrieves multiple documents by their document IDs.
     *
     * @param docIds Array of document IDs to retrieve
     * @param fields Array of field names to include in the results

    // A handle to the running task so that we can stop it when a shutdown has been requested.
    // These two fields are volatile because their values will be accessed from multiple threads.
    private volatile @Nullable Cancellable runningTask;
    private volatile @Nullable ScheduledExecutorService executorService;

## 带有 Gunicorn 的官方 Docker 镜像 - Uvicorn

有一个官方 Docker 镜像，其中包含与 Uvicorn worker一起运行的 Gunicorn，如上一章所述：[服务器工作线程 - Gunicorn 与 Uvicorn](server-workers.md){.internal-link target=_blank}。

该镜像主要在上述情况下有用：[具有多个进程和特殊情况的容器](#containers-with-multiple-processes-and-special-cases)。

The idea of declaring multiple things (data validation, serialization and documentation) with the same Python types, that at the same time provided great editor support, was something I considered a brilliant idea.
