vuepress2使用docsearch插件facetFilters多个lang参数，导致搜索不到内容

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

vuepress2使用docsearch插件的时候facetFilterslang会多一个lang:zh-CN的参数，导致搜索不到内容。 vuepress2下使用docsearch的依赖逻辑：plugin-docsearch → docsearch → algoliasearch 只需要修改打开node_modules/@vuepress/plugin-docsearch/lib/client/components/Docsearch.js文件 删掉lang:${lang.value}即可 删除脚本

cd node_modules/@vuepress/plugin-docsearch/lib/client/components/

# 去掉 lang 对象

sed -i .js s/\`lang:\$\{lang.value\}\`,//g Docsearch.js

目前不清楚是plugin-docsearch的bug还是我的algolia配置文件问题。

Github上有相关的问题 Docsearch not working，不过没太看明白，没找到解决方案。

我的配置项目，可以参考以下

   docsearchPlugin({
      // 配置项
      appId: '***',
      apiKey: '***',
      indexName: 'jaqi.note',
      contextualSearch: true,

      },

        '/': {

            },

                cancelButtonText: '取消',

            },
          },
        },
      },
