Question

我有一些带有一些嵌套字段的简历索引。我正在运行以下代码来获取具有Ruby技能和计算机教育的简历。

GET /resume/candidates/_search
{
    "query": {
        "nested" : {
            "path" : "sections",
            "query" : {
                "bool" : {
                  "must": [
                    {"match": {"sections.skills": "Ruby"}}
                  ], 
                    "filter" : [
                    { "term" : {"sections.education": "computer"} }
                    ]
                }
            }
        }
    }
}

当我单独运行时，bool和过滤器查询会给出正确的结果。但是当我把它们组合起来时，它们没有结果。我的索引中有一份简历，其中包括技能ruby和受过教育的计算机。

或者，目前我将离开乐谱部分，并将两者置于以下相同的条件下：

GET /resume/candidates/_search
{
    "query": {
        "nested" : {
            "path" : "sections",
            "query" : {
                "bool" : {
                  "must": [
                    {"match": {
                      "sections.skills": "Ruby"}},

                    {"match": {
                      "sections.education": "computer"}}

                  ]
               }
            }
        }
    }
}

它仍然不会返回任何结果，但如果单独写，它会返回结果。有人可以帮忙吗？

拥有你的映射会很高兴。顺便说一下，我尝试使用此代码创建您的场景，并且查询有效：

首先定义映射

PUT resume
{
  "mappings": {
    "candidates": {
      "properties": {
        "sections": {
          "type": "nested",
          "properties": {
            "skills": {
              "type": "text"
            },
            "education": {
              "type": "keyword"
            }
          }
        }
      }
    }
  }
}

然后添加两个候选人：

PUT resume/candidates/1
{
  "sections": [
    {
      "skills": "Ruby",
      "education": "computer"
    },
    {
      "skills": "elastic",
      "education": "computer"
    }
  ]
}


PUT resume/candidates/2
{
  "sections": [
    {
      "skills": "kibana",
      "education": "computer"
    },
    {
      "skills": "elastic",
      "education": "computer"
    }
  ]
}

这是查询：

GET resume/candidates/_search
{
  "query": {
    "nested": {
      "path": "sections",
      "query": {
        "bool": {
          "must": [
            {
              "term": {
                "sections.education": {
                  "value": "computer"
                }
              }
            },
            {
              "match": {
                "sections.skills": "Ruby"
              }
            }
          ]
        }
      }
    }
  }
}

它只返回第一个canidate：

{
  "took": 11,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 0.87546873,
    "hits": [
      {
        "_index": "resume",
        "_type": "candidates",
        "_id": "1",
        "_score": 0.87546873,
        "_source": {
          "sections": [
            {
              "skills": "Ruby",
              "education": "computer"
            },
            {
              "skills": "elastic",
              "education": "computer"
            }
          ]
        }
      }
    ]
  }
}
