I am working on the synonyms search in nest 7.5. Do you have example for it? Most examples online are for old version nest.
What is the replacement for .createIndex in nest 7.5?

Here is my current code, but it does not work
public void setIndex(ElasticClient client, List Users)
{
```
client.Indices.Delete("user");
var user = Users[0];
client.Bulk(b => b
.Index("user")
.IndexMany(Users)
);
var analyzeResponse = client.Indices.Analyze(a => a
.Analyzer("standard")
.Text("F# is THE SUPERIOR language :)")
);
client.Indices.UpdateSettings("analysis-index", i => i
.IndexSettings(s => s
.Analysis(a => a
.TokenFilters(t => t.NGram("nGram", n => n.MinGram(2)
.MaxGram(20)))
.CharFilters(cf => cf
.Mapping("my_char_filter", m => m
.Mappings("F# => FSharp")
)
)
.TokenFilters(tf => tf
.Synonym("my_synonym", sf => sf
.Synonyms("superior, great")
)
)
.Analyzers(an => an
.Custom("my_analyzer", ca => ca
.Tokenizer("standard")
.CharFilters("my_char_filter")
.Filters("lowercase", "stop", "my_synonym")
)
)
)
)
);
}
```
```auto
```
