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"
}


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 ?
