python - Elasticsearch不允许我添加较长的字典[TransportError(400)]

Question

我正在使用elasticsearch-py在 flex 索引中添加一些字典，
我将字典添加到索引和包含列表的字典，在我的代码中添加了该字典，但它给了我这样的错误:
RequestError: TransportError(400, u'mapper_parsing_exception', u'failed to parse [long_spec]')搜索后，我得到了我应该在 flex 图中添加一些 map ，然后在映射中添加"long_spec":{ "type": "text" }和其他测试"long_spec"{ "type": "string" }的方法，但是它不起作用。

我在python中使用它self.es.index(index="new_index", doc_type='user',body=dict)我的字典是这样的:

每当您要索引的字段的类型与指定的映射不同时，就会得到mapper_parsing_exception。对于您而言， long_spec 字典在各个文档中必须具有不同的数据类型，因此会出现错误。您可以按照以下步骤复制错误:

尝试建立文件索引

PUT regexpindex/product/4
{ 
    "documentId": 1234,
    "someOtherInfo": "Product1\\Product1",
    "permissions": ["a", "b", "c", "g"]
}

尝试用documentId字段的字符串数据类型索引另一个文档

PUT regexpindex/product/4
{ 
    "documentId": "some-string",
    "someOtherInfo": "Product1\\Product1",
    "permissions": ["a", "b", "c", "g"]
}

然后您将获得mapper_parsing_exception。

请确保所有文档的所有字段都具有相同的数据类型。如果您认为这些文档的格式有误，也可以忽略这些文档。了解有关 here的更多信息。
