elasticsearch - elasticsearch 6无法安装插件org.wikimedia.search:extra不兼容

Question

我已经在docker上安装了 flex 搜索版本6.2.3。

尝试安装以下elasticsearch插件时遇到以下错误

org.wikimedia.search:extra

线程“主”中的异常java.lang.IllegalArgumentException:插件[extra]与版本[6.2.3]不兼容；是为版本[5.5.2]设计的

我尝试使用以下命令安装插件:

RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install org.wikimedia.search:extra:5.5.2.3

我正在尝试安装此插件以将Wikipedia词典加载到elasticsearch中，但该插件的最新版本为5.5.2。

两年前，维基媒体提供了生产 flex 搜索索引的转储。因此，将维基百科(也是维基百科)加载到 flex 中非常简单

索引每周导出一次，每个Wiki导出两次。

The content index, which contains only article pages, called content;
The general index, containing all pages. This includes talk pages, templates, etc, called general;

你可以在这里找到他们 http://dumps.wikimedia.org/other/cirrussearch/current/

根据您的需求创建一个映射。例如:

创建索引后，只需键入:

zcat enwiki-current-cirrussearch-general.json.gz | parallel --pipe -L 2 -N 2000 -j3 'curl -s http://localhost:9200/enwiki/_bulk --data-binary @- > /dev/null'
