我需要一些帮助来解读我的 ES 设置发生了什么。基本上，我使用自定义分析器（我们支持的每种语言一个）并在索引时为我们拥有的每个客户创建了多个索引。问题出现在搜索时，当我对所有客户的索引进行搜索时，一个特定的索引（英语）总是比其他语言排名更高，即使搜索的术语在该英语索引文档中出现的次数较少。
所以这就是我的 ES 设置：我们有多个客户端，每个客户端都可以上传多种语言的文档。因此，为了满足这一要求，我设置了根据 clientId 和语言命名的索引，即 A-en、A-de、A-fr、B-en、B-it 等（其中 A 和 B 是客户端 ID， -xx 是 ISO 语言代码）。每个索引都是使用该客户所需语言的自定义分析器创建的，并且每个字段都映射为在设置部分中使用这些自定义分析器，如下所示：这是一个英语索引设置，所有具有“英语”文档的客户都将被索引为：

所有语言索引都遵循这种模式（我们有 24 种不同的受支持语言），每个客户端在创建索引以及将文档索引到这些索引中时都将使用其中一种设置。
所以，这一切看起来都很好，ES 对此很满意。现在来到搜索查询，这就是事情变得混乱的地方。
我的搜索查询基于“短语必须优先于单个术语”的要求。此外，当客户端执行搜索时，必须在其所有文档和语言中执行该搜索（因此创建索引时使用名称中的客户端 ID）。这是通过在索引名称的 url 中使用通配符来实现的，即 /A-*/video/_search 将搜索所有客户端 A 文档，而不管语言如何。
这是我发布到服务器的搜索查询...

]
}
}
}
},
"params": {
"query_string": "Turkish"
}
}
}
}
请注意，我正在搜索“土耳其语”一词，并搜索所有语言。现在查看结果，并注意 *-en 索引在整个文档字段中返回的排名高于 *-tr（土耳其语）索引，后者包含单词“土耳其语”的次数更多。

I think that to many consumers worry buy about sustainability, What ultimately affects what you buy but above all, I would argue by me as a consumer, that I the companies consider myself, the same values as I have with regard to sustainability. I'm specifically going to shops that use less packaging or such which is easier to recycle can and if we can, we go to regional always walking or local shops if they are nearby. And many companies are trying the same products for sale, for a lower price But if a company can convince me that their products are more sustainable or safe for me and my environment. would I also be willing to pay more at the end. If a company claims to be sustainable. will I always find out in what way they are safer. There are so many eco-certificates and I don't know what you mean or whether they really are for sustainability. Perhaps there could be a decision, Consumers easier makes it,. understanding sustainable products that would be a great help for everyone.",
