Hi,

I use the context suggester, well, for suggestions and I have more than 256  
different categories.

When I try to index a document with 257 categories, I get the following  
error:

{  
"error":"IllegalArgumentException[TokenStream expanded to 257 finite  
strings. Only \<= 256 finite strings are supported]",  
"status":500  
}

I have uploaded a simple curl example  
here: [https://gist.github.com/goldmar/2c3f64575df420a5413a](https://gist.github.com/goldmar/2c3f64575df420a5413a)

Is this a bug or an expected limitation? How can I solve this problem (e.g.  
increase the number of possible categories)?

Also, please note that the documentation does not mention this  
limitation: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/suggester-context.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/suggester-context.html)

Best regards,  
Mark
