Create custom token filter with NEST

Question

How can I configure Index using NEST with such JSON:

\"settings\":{
  \"analysis\":{
     \"filter\":{
        \"name_ngrams\":{
           \"side\":\"front\

After some searching I've found a solution:

var partialName = new CustomAnalyzer
            {
                Filter = new List<string> {"lowercase", "name_ngrams", "standard", "asciifolding"},
                Tokenizer = "standard"
            };

var fullName = new CustomAnalyzer
            {
                Filter = new List<string> {"standard", "lowercase", "asciifolding"},
                Tokenizer = "standard"
            };

client.CreateIndex("indexname", c => c
                .Analysis(descriptor => descriptor
                    .TokenFilters(bases => bases.Add("name_ngrams", new EdgeNGramTokenFilter
                    {
                        MaxGram = 20,
                        MinGram = 2,
                        Side = "front"
                    }))
                    .Analyzers(bases => bases
                        .Add("partial_name", partialName)
                        .Add("full_name", fullName))
                )
                .AddMapping<Company>(m => m
                    .Properties(o => o
                        .String(i => i
                            .Name(x => x.Name)
                            .IndexAnalyzer("partial_name")
                            .SearchAnalyzer("full_name")
                        ))));
