我正在将Elastic search版本7.1.0和NEST 6.7.0与Elasticsearch.Net 6.7.0一起使用。 在尝试创建索引时，出现错误。
这是我的代码，我在NEST和Elasticsearch.Net 6.4.0版本上使用了相同的代码，并且运行正常
var result = Client.CreateIndex(DefaultIndex, c => c
.Settings(s => s
.NumberOfShards(numberOfShards)
.NumberOfReplicas(numberOfReplicas)
.BlocksReadOnly(false)
)
.Mappings(m => m
.Map<SearchDocument>(mm => mm
.AutoMap(3)
)
)
);
这是我得到的错误
从上把一个不成功的低电平呼叫建立无效NEST响应： / local_brainbank_index

我可能是错的，但据我记得在第7版中没有文档类型。
Elasticsearch 7.x
Specifying types in requests is deprecated. For instance, indexing a document no longer requires a document type. The new index APIs are PUT {index}/_doc/{id} in case of explicit ids and POST {index}/_doc for auto-generated ids. Note that in 7.0, _doc is a permanent part of the path, and represents the endpoint name rather than the document type.
The include_type_name parameter in the index creation, index template, and mapping APIs will default to false. Setting the parameter at all will result in a deprecation warning.
The _default_ mapping type is removed.
所以，您可能需要解决的问题是更新映射。您可以调整ConnectionSettings
public void Configure(ConnectionSettings connectionSettings)
{
connectionSettings
.DefaultMappingFor<User>(m => m
.TypeName("_doc")
.IndexName(_esConfig.CustomerIndexPattern)
.IdProperty(p => p.Id)
)
或此document指出您可能可以使用
[ElasticsearchType(Name = "_doc")]属性

NEST和Elasticsearch.Net 6.7.0与Elasticsearch 7.x不兼容。请使用NEST和Elasticsearch.Net 7.x，当前最新发布的是7.0.0-alpha2。
