elasticsearch - 通过在Elasticsearch中部分匹配来搜索字符串数组

Question

我有这样的 Realm :names: ["Red:123", "Blue:45", "Green:56"]它的映射是

"names": {
    "type": "keyword"
},

我怎么能这样搜索

{
  "query": {
    "match": {
      "names": "red"
    }
  }
}

获取red数组元素中names的所有文档？
现在它仅适用于

{
  "query": {
    "match": {
      "names": "red:123"
    }
  }
}

您可以添加multi fields或只将类型更改为text即可实现所需的结果
使用multi fields的索引映射

{
  "mappings": {
    "properties": {
      "names": {
        "type": "text",
        "fields": {
          "raw": { 
            "type":  "keyword"
          }
        }
      }
    }
  }
}

添加带有索引数据，映射，搜索查询和搜索结果的工作示例
索引映射:

{
  "mappings":{
    "properties":{
      "names":{
        "type":"text"
      }
    }
  }
}

索引数据:

{
  "names": [
    "Red:123",
    "Blue:45",
    "Green:56"
  ]
}

搜索查询:

{
  "query": {
    "match": {
      "names": "red"
    }
  }
}

搜索结果:

"hits": [
      {
        "_index": "64665127",
        "_type": "_doc",
        "_id": "1",
        "_score": 0.2876821,
        "_source": {
          "names": [
            "Red:123",
            "Blue:45",
            "Green:56"
          ]
        }
      }
    ]
