+# Fess: Enterprise-Suchserver
+[![Java CI with Maven](https://github.com/codelibs/fess/actions/workflows/maven.yml/badge.svg)](https://github.com/codelibs/fess/actions/workflows/maven.yml)
+[![Maven Central](https://maven-badges.herokuapp.com/maven-central/org.codelibs.fess/fess/badge.svg)](https://maven-badges.herokuapp.com/maven-central/org.codelibs.fess/fess)
+[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://github.com/gitbucket/gitbucket/blob/master/LICENSE)
+
+## Übersicht
+
+Fess ist ein sehr leistungsstarker und einfach zu implementierender Enterprise-Suchserver. Sie können Fess schnell auf jeder Plattform installieren und ausführen, auf der die Java-Laufzeitumgebung (JRE) läuft. Fess wird unter der [Apache-Lizenz 2.0](LICENSE) bereitgestellt.
+
+Fess basiert auf [OpenSearch](https://github.com/opensearch-project/OpenSearch), aber es ist kein Wissen oder Erfahrung mit OpenSearch erforderlich. Fess bietet eine einfach zu bedienende Administrations-GUI zur Konfiguration des Systems über Ihren Browser.
+Fess enthält auch einen Crawler, der Dokumente auf einem [Webserver](https://fess.codelibs.org/14.17/admin/webconfig-guide.html), [Dateisystem](https://fess.codelibs.org/14.17/admin/fileconfig-guide.html) oder [Datenspeicher](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html) (wie CSV oder Datenbank) durchsuchen kann. Viele Dateiformate werden unterstützt, einschließlich (aber nicht beschränkt auf): Microsoft Office, PDF und zip.
+
+*[Fess Site Search](https://github.com/codelibs/fess-site-search)* ist eine kostenlose Alternative zur [Google Site Search](https://enterprise.google.com/search/products/gss.html). Weitere Details finden Sie in der [Dokumentation des FSS JS Generators](https://fss-generator.codelibs.org/docs/manual).

+## Website
+
+[fess.codelibs.org](https://fess.codelibs.org/)
+
+## Probleme/Fragen
+
+[discuss.codelibs.org](https://discuss.codelibs.org/c/FessEN/)
+
+## Erste Schritte
+
+Es gibt zwei Möglichkeiten, Fess auszuprobieren. Die erste besteht darin, es selbst herunterzuladen und zu installieren. Die zweite besteht darin, [Docker](https://www.docker.com/products/docker-engine) zu verwenden.
+
+### Herunterladen und Installieren/Ausführen
+
+Fess 14.17 ist jetzt verfügbar und kann auf der [Release-Seite](https://github.com/codelibs/fess/releases "download") heruntergeladen werden. Downloads gibt es in drei Formaten: deb, rpm, zip.
+
+Die folgenden Befehle zeigen, wie der Zip-Download verwendet wird:
+
+    $ unzip fess-14.17.x.zip
+    $ cd fess-14.17.x
+    $ ./bin/fess
+
+Weitere Informationen finden Sie im [Installationshandbuch](https://fess.codelibs.org/14.17/install/index.html).
+
+### Docker
+
+Wir bieten Docker-Images auf [ghcr.io](https://github.com/orgs/codelibs/packages) an. Wir stellen auch eine Docker Compose (YAML)-Datei in [diesem Repository](https://github.com/codelibs/docker-fess/tree/master/compose) bereit.
+
+### Browser-Benutzeroberfläche
+
+- Suchoberfläche: http://localhost:8080/
+
+![Suchoberfläche](https://fess.codelibs.org/_images/fess_search_result1.png)

+
+## 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：
+
+    $ unzip fess-14.17.x.zip
+    $ cd fess-14.17.x
+    $ ./bin/fess
+
+詳細については、[インストールガイド](https://fess.codelibs.org/14.17/install/index.html)を参照してください。
+
+### Docker
+
+[ghcr.io](https://github.com/orgs/codelibs/packages)にDockerイメージを提供しています。また、このリポジトリにはDocker Compose（YAML）ファイルも用意されています。[こちらのリポジトリ](https://github.com/codelibs/docker-fess/tree/master/compose)で確認できます。
+
+### ブラウザUI
+
+- 検索UI: http://localhost:8080/
+
+![Search UI](https://fess.codelibs.org/_images/fess_search_result1.png)
+
+- 管理者UI: http://localhost:8080/admin/ （デフォルトのユーザー名/パスワードはadmin/adminです）
+
+![Admin UI](https://fess.codelibs.org/_images/fess_admin_dashboard.png)
+
+管理者UIでは、（Web、ファイル、データストア）クローラの設定ページでクロール対象を登録し、[スケジューラページ](https://fess.codelibs.org/14.17/admin/scheduler-guide.html)から手動でクローラを開始できます。

+## 开发信息
+
+### 获取源代码
+
+1. 克隆 Fess 的存储库：
+    ```
+    $ cd ~/workspace
+    $ git clone https://github.com/codelibs/fess.git
+    ```
+    
+2. 将克隆的存储库作为 [Maven](https://maven.apache.org/) 项目导入 [Eclipse](https://www.eclipse.org/eclipseide/) 或其他 IDE。
+
+### 设置 OpenSearch 插件
+
+运行 antrun:run 将插件下载到插件目录：
+
+    $ mvn antrun:run
+
+### 运行 Fess
+
+在您的 IDE 上运行或调试 `org.codelibs.fess.FessBoot`，然后访问 http://localhost:8080/
+
+### 构建包
+
+运行 `package` 目标，然后在 target/releases 中创建发布文件。
+
+    $ mvn package
+    $ mvn rpm:rpm   # .rpm 包
+    $ mvn jdeb:jdeb # .deb 包
+
+### 生成源代码
+
+    $ mvn dbflute:download # （仅运行一次）
+    $ mvn dbflute:freegen
+    $ mvn license:format
+
+### 集成测试
+
+启动 Fess 服务器并运行以下命令：
+
+    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201"
+
+要运行单个测试用例，您可以使用：
+
+    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201" -Dtest=SearchApiTests
+
+### 翻译为您的语言
+
+Fess 是国际化软件。
+
+如果您想为您的语言添加标签/消息，请翻译属性文件，然后将其重命名为 fess\_\*\_[lang].properties。
+
+* [fess_label_en.properties](https://github.com/codelibs/fess/blob/master/src/main/resources/fess_label_en.properties)
+* [fess_message_en.properties](https://github.com/codelibs/fess/blob/master/src/main/resources/fess_message_en.properties)
+
+对于搜索/索引分析器，如果 [doc.json](https://github.com/codelibs/fess/blob/master/src/main/resources/fess_indices/fess/doc.json) 包含您语言的 lang\_[lang]，请为您的语言修改分析器。有关分析器的更多详细信息，请参阅 [OpenSearch 文档](https://opensearch.org/docs/latest/analyzers/search-analyzers/)。
+
+我们欢迎您的语言的 Pull Request。
