Bonjour,  
J'ai un problème avec un fuzziness query pour retrouver des noms composés.  
Version ES : 5.4.1  
Ci dessous le scénario  
Je voudrais si j'ai un document "dupont"  
Le trouver en recherchant "dupond martin"

```
    # creation du template avec maping et analyzer
    PUT _template/test-template
    {
    	"template": "test-*",

# creation de l'index
PUT test-nom

# ajout d'un doc
PUT test-nom/personne/1
{
 "nom" : "dupont"
}

# Recherche nom composé avec un erreur sur le nom d au lieu de t
GET test-nom/_search
  {"query" : {
  "bool" : {
      "must": [
              {
                "match" : {
                    "nom" : {
                        "query" : " dupond martin",                            
                        "analyzer" : "test-analyzer",
                        "fuzziness" : "2",
                        "operator": "and", 
                        "prefix_length" : 0,
                        "max_expansions" : 1000,
                        "fuzzy_transpositions" : false,
                        "lenient" : false,
                        "zero_terms_query" : "NONE",
                          "boost" : 1.0
                          }
                    }
                
              }]
  }
  }  
  
  }

GET test-nom/_analyze
{
  "analyzer" : "test-analyzer",
  "text" : "dupond martin"
}

```

```auto

On voit bien que "dupond martin" est indexé selon les token 
"dupond"
"martin"
"dupond martin"

Je ne comprends pas pour quoi "dupont" ne match pas avec "dupond" avec un fuzziness de 2 ?
```
