我有一个 JSON 文档。当我尝试在 Elasticsearch 中编制索引时，出现异常。

index1 没有默认映射。

curl -XPOST localhost:9200/index1/talk?pretty=1 -d '
{
    "_id" : ObjectId("503b29efe4b032e338f0581b"),
    "_oid" : NumberLong(1182053),
    "_ugc" : false,
    "_v" : 22,
    "c" : [
        "Destination"
    ],
    "cc" : "AD",
    "co" : "andorra",
    "e" : true,
    "f" : [
        "Destination"
    ],
    "gi" : "3038999",
    "h" : 0,
    "i" : [ ],
    "k" : [
        "soldeu",
        "parroquia de canillo"
    ],
    "kv" : [
        "soldeu"
    ],
    "la" : 42.57688,
    "lc" : 0,
    "ln" : 1.66769,
    "ns" : [
        {
            "n" : "Soldeu",
            "l" : "en",
            "t" : "p"
        }
    ],
    "po" : 0,
    "point" : [
        42.57688,
        1.66769
    ]
}'

JSON 是来自 mongodb 的文档。我已经安装了以下插件:

ES_HOME/bin/plugin -install elasticsearch/elasticsearch-mapper-attachments/1.4.0 
ES_HOME/bin/plugin -install richardwilly98/elasticsearch-river-mongodb/1.4.0 

谁能告诉我哪里出错了？？

更新:

错误似乎是因为 ObjectId() 和 NumberLong()。但是，我不希望这些字段被索引，所以我定义了一个自定义映射来发出这些字段。 自定义映射:

curl -XPUT localhost:9200/index1?pretty=1 -d '{
        "mappings" : {
            "type1" : {
                "_all" : {"enabled" : false},
                "properties" : {
         "ns" : {
            "dynamic" : "true",
                "properties" : {
                  "n" : {
                    "type" : "string"
                  },
                  "l" : {
                    "type" : "string"
                  },
            "t" : {
                    "type" : "string"
                  }
        }
      }
                }
            }
        }
}'

理想情况下，_id 和 _oid 应该被分析器省略，但仍然有任何方法可以为此类对象提供映射。

ObjectId = org.bson.types.ObjectId and NumberLong = java.lang.Double

最佳答案

json 对象不正确。

您的 _id 属性似乎发生了一些奇怪的事情，因此 ElasticSearch 无法解析它。
