.net - 使用Nest创建弹性索引

Question

我在工作中(从Python)大量使用elasticsearch，但想将其应用到我在业余时间正在做的一个小型.Net项目中。快速浏览NuGet，将我带到Nest。

我正在定义我的“模型”，如下所示:

<ElasticType(Name:="Document")>
Public Class Document
    Property UserId As Long
    <ElasticProperty(IndexAnalyzer:="not_analyzed")>
    Property Something As String
    Property EmailAddress As String
End Class

然后尝试像这样创建和索引...

Dim Ret = ES.CreateIndex(IndexName,
               Function(x) x.AddMapping(Of Document)(
                   Function(m) m.MapFromAttributes))
If Not Ret.OK Then
    With Ret.ConnectionStatus.Error
        Throw New Exception(String.Format("Failed to create index ({0}): {1}", .HttpStatusCode, .ExceptionMessage))
    End With
End If

而且我得到 Failed to create index (BadRequest): MapperParsingException[mapping [Document]]; nested: MapperParsingException[Analyzer [not_analyzed] not found for field [something]];
我都尝试过

<ElasticProperty(Analyzer:="not_analyzed")>

和

<ElasticProperty(IndexAnalyzer:="not_analyzed")>

我想让它构建的是相当于json

"something" : {"type" : "string", "index" : "not_analyzed"}

如 es docs所示。

我想念什么？

我错过了处理此问题的属性属性...

<ElasticType(Name:="Document")>
Public Class Document
    Property UserId As Long
    <ElasticProperty(Index:=FieldIndexOption.not_analyzed)>
    Property Something As String
    Property EmailAddress As String
End Class

请注意带有一个Enum的 Index属性。感谢@geeky_sh提示我寻找正确的位置。
