ElasticSearch完成建议者标准分析器不起作用 [英] ElasticSearch completion suggester Standard Analyzer not working

问题描述

我们正在使用ElasticSearch 完成建议与标准分析器 ，但似乎文本未标记化.

We're using ElasticSearch completion suggester with the Standard Analyzer, but it seems like the text is not tokenized.

例如

文本:第一个示例"，第二个示例"

Texts: "First Example", "Second Example"

搜索:"Fi"返回第一个示例"

Search: "Fi" returns "First Example"

而

搜索:"Ex"不返回任何结果，返回第一个示例"

Search: "Ex" doesn't return any result returns "First Example"

推荐答案

作为Elastic关于完成建议的文档:

As the doc of Elastic about completion suggester: Completion Suggester

完成建议者是所谓的前缀建议者.

The completion suggester is a so-called prefix suggester.

因此，当您发送关键字时，它将寻找文本的前缀.

So when you send a keyword, it will look for the prefix of your texts.

例如:

搜索:"Fi" =>第一个示例"

Search: "Fi" => "First Example"

搜索:秒" =>第二个示例"

Search: "Sec" => "Second Example"

但是如果您给Elastic提供"Ex"，它将不会返回任何内容，因为它找不到以"Ex"开头的文本.

but if you give Elastic "Ex", it returns nothing because it cannot find a text which begins with "Ex".

您可以尝试其他一些建议，例如:字词提示

You can try some others suggesters like: Term Suggester
