匹配弹性搜索中的精确短语(Matching exact phrase in elastic search)

 所以我有这样的查询： 
 
{  
   "from":0,
   "size":20,
   "sort":{  
      "prices_count":"desc"
   },
   "query":{  
      "bool":{  
         "must":[  
            {  
               "terms":{  
                  "category_ids":[  
                     "3"
                  ]
               }
            },     
            {  
               "nested":{  
                  "path":"specs",
                  "query":{  
                     "bool":{  
                        "must":[  
                           {  
                              "match_phrase":{  
                                 "specs.model":"iphone-6s"
                              }
                           }
                        ]
                     }
                  }
               }
            }
         ]
      }
   }
}
 
 我的问题在于嵌套查询部分。 specs.model查询不仅匹配模型iphone-6s文档，而且匹配iphone-6s-plus文档，我也尝试使用term匹配，但是后来我没有得到任何结果。 有任何想法吗？ 

So i have a query like this:
 
{  
   "from":0,
   "size":20,
   "sort":{  
      "prices_count":"desc"
   },
   "query":{  
      "bool":{  
         "must":[  
            {  
               "terms":{  
                  "category_ids":[  
                     "3"
                  ]
               }
            },     
            {  
               "nested":{  
                  "path":"specs",
                  "query":{  
                     "bool":{  
                        "must":[  
                           {  
                              "match_phrase":{  
                                 "specs.model":"iphone-6s"
                              }
                           }
                        ]
                     }
                  }
               }
            }
         ]
      }
   }
}
 
My problem lies in the nested query part. the specs.model query matches not just documents with model iphone-6s, but the ones with iphone-6s-plus, I tried with term matching too, but then I get no results what so ever. Any ideas?
