Wildcard with exact phrase search using query_string

[telebh (Hanan)]

that's very helpful, many thanks Jimczi. is there away also run exact phrase search including wildcard using "query_string"
for example:

{  
               "query_string":{  
                  "query": "\"imperial college lond?n\"",
                  "fields": ["afdoc.affil"]
               }
            }
