多字段匹配查询 [英] Query with match by multiple fields

问题描述

我是弹性搜索的新手，想编写一个关注两个字段的查询.我的意思是字段的内容包含指定的子字符串.我有一个包含字段的文档，如下所示:

I'm pretty new to elastic search and would like to write a query that is concerned about two fields. I mean the content of the fields contains the specified substring. I have a document containing fields, like this:

name: n
tag: t

我试过了:

/_search -d '
{
    "query": {
        "match": {
             "name": "n",
             "tag": "t"
        }
    }
}

但是查询导致如下错误:

But the query results in the following error:

[match] 查询以简化形式解析，具有直接字段名称，但包括更多的选项，而不仅仅是字段名称，可能使用它的'options' 表单，带有 'query' 元素?

[match] query parsed in simplified form, with direct field name, but included more options than just the field name, possibly use its 'options' form, with 'query' element?

有没有办法在弹性搜索中做到这一点?

Is there a way to do this in elasticsearch?

推荐答案

您需要在 bool/must 查询中包含两个 match 查询，如下所示:

You need two match queries enclosed in a bool/must query, like this:

{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "name": "n"
          }
        },
        {
          "match": {
            "tag": "t"
          }
        }
      ]
    }
  }
}
