The following section of the documentation is wrong:
  
  
    
        
           | 
           ### Search hinted user [POST /users/search_hinted_user]  | 
        
    
   
 
With AirDC++w 2.11.1 x86_64 the request does not work with the structure:
{
    "cid": "YXZ",
    "hub_url": "any-hub"
} 
It must have the following structure to be processed successfully:
{
  "user": {
    "cid": "YXZ",
    "hub_url": "any-hub"
  }
}
