确定哪些词在模糊搜索中匹配 [英] Determining which words were matched in a fuzzy search

问题描述

我正在运行模糊搜索，需要查看匹配的单词.例如，如果我正在搜索查询 testing，并且它与带有句子 The boy was resting 的字段匹配，我需要能够知道匹配是由于resting这个词.

I'm running a fuzzy search, and need to see which words were matched. For example, if I am searching for the query testing, and it matches a field with the sentence The boy was resting, I need to be able to know that the match was due to the word resting.

我尝试设置参数explain = true，但它似乎没有包含我需要的信息.有什么想法吗?

I tried setting the parameter explain = true, but it doesn't seem to contain the information I need. Any thoughts?

推荐答案

好的，这就是我要找的:

Alright, this is what I was looking for:

经过一番研究，我找到了 elasticsearch 的突出显示功能.

After a bit of research, I found the Highlighting feature of elasticsearch.

默认情况下，它返回围绕匹配的上下文片段，但您可以将片段大小设置为查询长度以仅返回完全匹配.例如:

By default it returns a snippet of context surrounding the match, but you can set the fragment size to the query length to return only the exact match. For example:

{
    query : query,
    highlight : {
        "fields" : {
            'text' : {
                "fragment_size" : query.length
            }
        }
    }
}
