python - 在 Elasticsearch 中的某些字段上禁用搜索

Question

我只想在一个字段“XYZ”中搜索。我正在使用下面的代码，但这给了我错误。你能帮我吗？

{
  "dynamic": "false",
  "properties": {
    "ABC": {
      "type": "text",
      "index": false,
      "store": true
      
    },
    "PQR": {
      "type": "text",
       "index": false,
      "store": true
    },
    "XYZ": {
      "type": "text"
    }
  }
}

附言我希望将字段“ABC”和“PQR”存储在 flex 搜索中，但我也想禁用对这些字段的搜索。

您可以使用enabled mapping parameter

The enabled setting, which can be applied only to the top-levelmapping definition and to object fields, causes Elasticsearch to skipparsing of the contents of the field entirely. The JSON can still beretrieved from the _source field, but it is not searchable or storedin any other way:

索引映射:

{
  "mappings": {
    "properties": {
      "ABC": {
        "enabled":false
      },
      "PQR": {
        "enabled":false
      },
      "XYZ": {
        "type": "text"
      }
    }
  }
}

索引数据:

{
    "ABC": "b",
    "PQR": "c",
    "XYZ": "a"
}

搜索查询:
在 PQR字段上搜索时，没有搜索结果。

{
  "query": {
    "match": {
      "PQR": {
        "query": "c"
      }
    }
  }
}

搜索结果:

"hits": {
    "total": {
      "value": 0,
      "relation": "eq"
    },
    "max_score": null,
    "hits": []
  }

搜索查询:

{
  "query": {
    "match": {
      "XYZ": {
        "query": "a"
      }
    }
  }
}

搜索结果:

"hits": [
      {
        "_index": "stof_64113718",
        "_type": "_doc",
        "_id": "1",
        "_score": 0.13353139,
        "_source": {
          "ABC": "b",
          "PQR": "c",
          "XYZ": "a"
        }
      }
    ]
