I am new in Elastic search and i want to use it for Phonetic search so I have added plugin NEST in dotnet (C#) using nougat package and also installed phonetic analysis plugin then tried to create index with phonetic but getting following error.

ServerError = {ServerError: 400Type: illegal\_argument\_exception Reason: "Unknown filter type [phonetic] for [my\_metaphone]"}

**Code :**

var result = client.CreateIndex("indexName", i =\> i  
.Settings(s =\> s  
.Analysis(a =\> a  
.Analyzers(x =\> x.Custom("my\_analyzer", ca =\> ca.Filters("standard", "lowercase", "my\_metaphone")))  
.TokenFilters(x =\> x.Phonetic("my\_metaphone", pf =\> pf.Encoder(PhoneticEncoder.DoubleMetaphone)))  
))  
.Mappings(m =\> m  
.Map(mm =\> mm  
.AutoMap()  
.Properties(p =\> p  
.Text(t =\> t  
.Name(n =\> n.Name)  
.Analyzer("my\_analyzer")  
.SearchAnalyzer("my\_analyzer")  
)  
)  
)  
)  
);

Can any one help me to create index with phonetic configuration in dotnet?  
I am able to create index with below json request.

**Code :**

PUT /indexname

"index": {

Using C# LINQ scenario, it's not working, Can any one guide for the same?  
Thanks in Advance,
