Pharse suggester with field search in query syntax

I am trying to implement "did you mean" feature using the elasticsearch phrase suggester.
It works OK, except when using field search in query syntax.

The query syntax I use is Query String Query

Here is an example of a query:

{
  "from" : 0,
  "size" : 10,
  "query" : {
    "query_string" : {
      "query" : "defect.fields.description:(tetsing)",
      "use_dis_max" : true
    }
  },
  "suggest" : {
    "phrase-suggest-iris" : {
      "text" : "defect.fields.description:(tetsing)",
      "phrase" : {
        "analyzer" : "default",
        "field" : "_all",
        "max_errors" : 2.0,
        "highlight" : {
          "pre_tag" : "<b>",
          "post_tag" : "</b>"
        }
      }
    }
  }
}

And here is what I get in the suggestions:

defect.fields.description testing

The ":" is missing from the suggestions and other operators like "()".
It seems like the suggeter does not keep query syntax.

Any help/suggestion would be appreciated.

Thanks!

Because of the default analyser, which splits things up and would remove those non-alphas.
You may want to look at setting that non-analyzed instead.

What do you mean by not_analyzed? I think it is not a valid value for "analyzer", plus I do want the suggester to analyze the text because I all my fields are analyzed and I need it to break the words, I just want it to keep lucene query string language.
I can also have complex searches that combine free text search with field search, e.g.:

"query_string" : { "query" : "login failed defect.fields.description:(tetsing)", "use_dis_max" : true }
