Question

好吧也许我错过了Elasticsearch的一些核心概念，但我是新手，并试图找到对我来说合理的东西。

让我们想象一下，我们在比赛中有很多选手，赛道周围有检查站。

基础文档可能如下所示：

{
    "name"       : "John Smith",
    "age"        : "31",
    "checkpoints": [
        {
            "checkpoint" : "Race Start"
            "timestamp"  : "..."
        }
    ]
 }

我的问题是，能否扩展检查点列表是否有意义，如果是，那么做一个示例（POST）请求会是什么？

预期结果：

{
    "name"       : "John Smith",
    "age"        : "31",
    "checkpoints": [
        {
            "checkpoint" : "Race Start"
            "timestamp"  : "..."
        },
        {
            "checkpoint" : "Checkpoint1"
            "timestamp"  : "..."
        },
        {
            "checkpoint" : "Checkpoint2"
            "timestamp"  : "..."
        }
    ]
 }

您无需做具体的事情。

运行PUT查询时：

curl -XPUT localhost:9200/your_index/your_type/1 -d '{
    "name"       : "John Smith",
    "age"        : "31",
    "checkpoints": [
        {
            "checkpoint" : "Race Start",
            "timestamp"  : "..."
        }
    ]
}'

您将在GET查询中获得完全相同的内容：

curl -XGET localhost:9200/your_index/your_type/1

结果：

{"_index":"your_index","_type":"your_type","_id":"1","_version":2,"found":true,"_source":{
        "name"       : "John Smith",
        "age"        : "31",
        "checkpoints": [
            {
                "checkpoint" : "Race Start",
                "timestamp"  : "..."
            }
        ]
    }}

所以，当你跑：

curl -XPUT localhost:9200/your_index/your_type/1 -d '{
    "name"       : "John Smith",
    "age"        : "31",
    "checkpoints": [
        {
            "checkpoint" : "Race Start",
            "timestamp"  : "..."
        },
        {
            "checkpoint" : "Checkpoint1",
            "timestamp"  : "..."
        },
        {
            "checkpoint" : "Checkpoint2",
            "timestamp"  : "..."
        }
    ]
}'

您将获得：

{"_index":"your_index","_type":"your_type","_id":"1","_version":3,"found":true,"_source":{
        "name"       : "John Smith",
        "age"        : "31",
        "checkpoints": [
            {
                "checkpoint" : "Race Start",
                "timestamp"  : "..."
            },
            {
                "checkpoint" : "Checkpoint1",
                "timestamp"  : "..."
            },
            {
                "checkpoint" : "Checkpoint2",
                "timestamp"  : "..."
            }
        ]
    }}
