Question

我正在尝试使用elasticsearch completion suggester。我有app_user对象，它们通过couchdb河进入我的弹性搜索实例。

这是我使用的映射：

{
    "app_user" : {
        "_all" : {"enabled" : true},
        "_source" : {
            "includes" : [
                "_id",
                "_rev",
                "type",
                "profile.callname",
                "profile.fullname",
                "email"
            ]
        },
        "properties" : {
            "suggest" : { "type" : "completion",
                          "index_analyzer" : "simple",
                          "search_analyzer" : "simple",
                          "payloads" : true
            }
        },
        "transform" : [
            {"script": "ctx._source.suggest = ['input':[ctx._source.email, ctx._source.profile.fullname, ctx._source.profile.callname]]"},
            {"script": "ctx._source.suggest.payload = ['_id': ctx._source['_id'], 'type': ctx._source['type'], '_rev': ctx._source['_rev']]"}
            ,
            {"script": "ctx._source.suggest.payload << ['label': ctx._source.profile.fullname, 'text': ctx._source.email]"}
        ]
    }
}

所以我试图在有效载荷中包含对象ID和显示文本。当我通过http://localhost:9200/myindex/app_user/<someid>?pretty&_source_transform查看生成的文档时，一切似乎都正常：

{
    "_index": "myindex",
    "_type": "app_user",
    "_id": "<someid>",
    "found": true,
    "_source": {
        "_rev": "2-dcd7b9d456e205d3e9d859fdc2c6a688",
        "_id": "<someid>",
        "email": "joni@example.org",
        "suggest": {
            "input": [
                "joni@example.org",
                ...
            ],
            "output": "joni surname - joni@example.org",
            "payload": {
                "_id": "<someid>",
                "type": "app_user",
                "_rev": "2-dcd7b9d456e205d3e9d859fdc2c6a688",
                "label": "joni surname",
                "text": "joni@example.org"
            }
        },
        "type": "app_user",
        "profile": {
            "callname": "",
            "fullname": "joni surname"
        }
    }
}

但是，当我尝试通过_suggest获取文档时，elasticsearch API会以某种方式破坏JSON对象payload：

curl -XGET "http://localhost:9200/myindex/_suggest" -d '{
    "all-suggest": {
        "text": "joni",
        "completion": {
            "field": "suggest"
        }
    }
}'

结果

{"_shards":{"total":5,"successful":5,"failed":0},"all-suggest":[{"text":"joni","offset":0,"length":5,"options":[{"text":"joni surname - joni@example.org","score":1.0,"payload"::)
�_id`<someid>�typeIapp_user�_reva2-dcd7b9d456e205d3e9d859fdc2c6a688�label�joni surname�textSjoni@example.org�}]}]}

绝对没有有效的JSON ..有什么想法吗？

这实际上是elasticsearch中的一个错误。已报告并确认here，应为fixed shortly。
