通过多个字段进行匹配查询 [英] Query with match by multiple fields

问题描述

我对弹性搜索还很陌生，想编写一个涉及两个字段的查询.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

我尝试过:

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

但是查询会导致以下错误:

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，但是不仅包含字段名称，还包含更多选项，可能使用其带有查询"元素的选项"形式?

[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?

elasticsearch中有没有办法做到这一点?

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"
          }
        }
      ]
    }
  }
}
