确定在模糊搜索中哪些词匹配 [英] Determining which words were matched in a fuzzy search

问题描述

我正在进行模糊搜索，需要查看哪些词匹配。例如，如果我正在搜索测试的查询，并且它与一个字段与句子匹配。男孩休息我需要知道匹配是由于休息。

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 ，但它似乎不包含我需要的信息。任何想法？

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

Alright, this is what I was looking for:

经过一番研究，我发现突出显示功能

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

默认情况下，它返回匹配项的上下文片段，但您可以将片段大小设置为查询长度，以仅返回完全匹配项。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
            }
        }
    }
}
