I'm using NEST v2.0 and trying to build a query such that when I search for a term that is in the index it will return that exact matches first along with possible fuzzy terms that are like the query but if I search for a term that's not in the index it will return fuzzy like terms or none if the initial query is way off.  
I read online that I should merge both my fuzzy and exact query using bool and should and use boost to give exact matches a higher priority if found so that it returns first on the page.The problem is when I search for a number it sometimes shows terms that are not even close or fuzzy terms before exact matches and when I search for fuzzy names(with one letter difference) no matches are found. How may I modify the query below to get desired results

```
 x => x.
          Query(q => q
              .Bool(b => b
                       .Should(s => s
                               .Fuzzy(c => c
                                 .Name("named_query")
                                 .Boost(1.1)
                                 .Field("_all")
                                 .Fuzziness(Fuzziness.Auto)
                                 .Value(query)
                                 .MaxExpansions(100)
                                 .PrefixLength(3)

                            )).Should(l => l
                                   .QueryString(y => y
                                         .DefaultField("_all")
                                         .Query(query)
                                         .Boost(10.0)
                                         ) )))
```
