When creating Tokenizers, I want to use the following pattern:  
@Tokenizers(tokenizers =\> tokenizers.Pattern("nuget-id-tokenizer", p =\> p.Pattern(@" **\wа-яА-Я+**"))  
But it doesn't work, although it works great in an online regular expression editor.  
This expression returns me spaces instead of words. Stack .net C#. What am I doing wrong?
