Hi,  
When using Completion Suggester with a Context, i note it is not possible to context\_type field as an indexing field (lowercase or uppercase ....).  
To test, you can use the same example in doc :  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#context-suggester](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#context-suggester)

Search for is OK :  
...  
"contexts": {  
"place\_type": ["cafe"]  
}

but KO for :  
...  
"contexts": {  
"place\_type": ["Cafe"]  
}  
.....

Can someone explane me what it is not working.

Thanks

i aslo see for performance issue, empty context is not allow at version \>= 7.0.0.

Perhap in the same way, they not allow at index time to analyse context\_type
