i realise i need to add this at the point of indexing but am not sure how... heres my existing index create

clientTEST.CreateIndex(c =\> c  
.Index("testcontent")  
.InitializeUsing(indexSettings)  
.AddMapping(m =\> m  
.MapFromAttributes()  
.IndexAnalyzer("english")  
.SearchAnalyzer("english"))  
);
