## はじめに

Fessを試す方法は2つあります。1つは自分でダウンロードしてインストールする方法、もう1つは[Docker](https://www.docker.com/products/docker-engine)を使用する方法です。

### ダウンロードおよびインストール/実行

Fess 14.17が利用可能で、[リリースページ](https://github.com/codelibs/fess/releases "download")からダウンロードできます。ダウンロードには、deb、rpm、zipの3つの形式があります。

以下のコマンドは、zipファイルを使用する例です：

│   └── service/             # Core services
├── fess-crawler-lasta/       # LastaFlute DI integration
└── fess-crawler-opensearch/  # OpenSearch backend
```

### Key Components

#### Core Engine
- **Crawler**: Main orchestrator managing crawl execution
- **CrawlerContext**: Execution context and configuration
- **CrawlerThread**: Individual crawler thread implementation

#### Client Architecture
