有没有办法从弹性搜索亮点中排除特定术语？

Question

我正在弹性搜索（6.0 版）中尝试一个查询，其中我有一个基本查询，最重要的是，我应用了过滤器来缩小搜索范围。如下：

GET target_index/_search
{
  "from": {start},
  "size": {offset},
  "_source": [
    "id",
    "name",
    "email",
    "company",
    "created_at",
  ],
  "query": {
    "bool": {
      "filter": {
        "bool": {
          "filter": [
            { "terms":{"name.raw": ["test","test2"] }},
            { "terms":{"email.raw": ["test@test.com","test2@test.com"] }} 
          ]
        }
      },
      "must": {
        "query_string": {
          "query": "test",
        }
      }
    }
  },
  "highlight": {
    "fields": {
      "*":{
        "type":"plain"
      }
    }
  }
}

当前结果-

{
  "took": 5,
  "timed_out": false,
  "_shards": {
    "total": 3,
    "successful": 3,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 1.90374,
    "hits": [
      {
        "_index": "index_name",
        "_id": "my_id",
        "_score": 1.90374,
        "_source": {
          "id": 2,
          "name": "test", 
          "email": "test@test.com",
          "company": "test company"
        },
        "highlight": {
          "name.raw": [
            "<em>test</em>"
          ],
          "name": [
            "<em>test</em>"
          ],
          "company": [
            "<em>test</em> company"
          ]
        }
      }
    ]
  }
}

想要的结果 -

{
  "took": 5,
  "timed_out": false,
  "_shards": {
    "total": 3,
    "successful": 3,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 1.90374,
    "hits": [
      {
        "_index": "index_name",
        "_id": "my_id",
        "_score": 1.90374,
        "_source": {
          "id": 2,
          "name": "test", 
          "email": "test@test.com",
          "company": "test company"
        },
        "highlight": {
          "company": [
            "<em>test</em> company"
          ]
        }
      }
    ]
  }
}

在这里，在所需结果的突出显示中，我不想要“name”和“name.raw”的数据。不应仅针对此特定查询搜索此字段，因此我无法完全禁用该字段的搜索。

我有很多术语，无法指定要包含在查询中的每个术语。有没有办法只从查询搜索中排除几个字段？

Answer 1

除了排除某些字段，您可以只包含您需要的那些：

{
  "query": {
    ...
  },
  "highlight": {
    "fields": {
      "company":{          <---
        "type":"plain"
      }
    }
  }
}
