如何在Elasticsearch中搜索查询的文档？

Question

我是Elasticsearch的新手，我面临一个问题。我的任务是搜索一组文档。例如，我有这样结构的数据：

type Doc struct{
   id string
   project_id string
   code string
   name string
   status string
}

但是困难的是，我如何获取所有带有project_id=abc的文档，然后通过与关键字“测试”匹配的任何其他字段（代码、名称、状态）搜索它们（例如）。我如何在Elasticsearch查询中做到这一点，请帮助我！

谢谢

Answer 1

这是我的解决办法

GET /[index_name]/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "query": "some text here"
          }
        }
      ],
      "filter": [
        {
          "term": {
            "project_id.keyword": "abc"
          }
        }
      ]
    }
  }
}

您可以使用与其他查询的布尔组合匹配的文档匹配的布尔查询。

必须与逻辑与运算符相同，应该与逻辑与运算符相同

添加具有索引数据、搜索查询和搜索结果的工作示例

索引数据：

{
  "id": 2,
  "project_id":"abc",
  "code": "a",
  "name":"bhavya",
  "status":"engineer"
}
{
  "id": 1,
  "project_id":"abc",
  "code": "a",
  "name":"bhavya",
  "status":"student"
}
{
  "id": 3,
  "project_id":"def",
  "code": "a",
  "name":"deeksha",
  "status":"engineer"
}

搜索查询：

给定查询满足以下条件："project_id"="abc"AND"name"："bhavya"AND"status"："学生"

{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "project_id": "abc"
          }
        },
        {
          "match": {
            "name": "bhavya"
          }
        },
        {
          "match": {
            "status": "student"
          }
        }
      ]
    }
  }
}

搜索结果：

"hits": [
      {
        "_index": "stof_64274465",
        "_type": "_doc",
        "_id": "1",
        "_score": 1.7021472,
        "_source": {
          "id": 1,
          "project_id": "abc",
          "code": "a",
          "name": "bhavya",
          "status": "student"
        }
      }
    ]
