Hi,

I have been using Elasticsearch through Nest (.NET technology) for a while now. I am currently working on an application where the user can do some search and more precisely looking for someone by typing an email for example.

After some tests and some research, I noticed that working on emails will request to set an uax\_url\_email tokenizer while creating the given index. Sadly, I have some issue to set this setting correctly and I can't retrieve the users while typing their email. Here is my code:

> var result = client?.CreateIndex(indexName, i =\> i
> 
> // Auto mapping with our UserModel entity  
> .Mappings(ms =\> ms.Map(m =\> m.AutoMap()))
> 
> // Setting an analyzer to use an uax\_url\_email tokenizer  
> .Settings(s =\> s.Analysis(a =\> a.Analyzers(aa =\> aa.Custom("my\_analyzer", t =\> t.Tokenizer("my\_tokenizer"))).Tokenizers(n =\> n.UaxEmailUrl("my\_tokenizer", t =\> t)))));

As the second comment is saying, I am using an analyzer to use the needed tokenizer since I can't find any attribute working with this last one for the Attribute Mapping:

> [Text(Analyzer = "my\_analyzer")]  
> public string Email { get; set; }

If anyone has some time, could you guys help me with this situation ? Otherwise, is there an attribute that I may not be aware of for the tokenizer and that will prevent me to create the analyzer ?

I thank you in advance and wish you a great day !  
Best regards,

Hi guys,

Sorry, but the issue was coming from my test. The above code is working perfectly fine !

N.B.: When I copied-pasted my code, I forgot a piece of it:

> // Auto mapping with our UserModel entity  
> .Mappings(ms =\> ms.Map(m =\> m.AutoMap()))
> 
> // Shoud be:
> 
> // Auto mapping with the UserModel entity  
> .Mappings(ms =\> ms.Map/\</UserModel/\>/(m =\> m.AutoMap()

EDIT: Apparently, it was the quote system that removed the missing part... Remove the for '/' characters to retrieve the correct code.

Best regards,
