得分的文件6.2.0

我在Lucene的查询6.2.0是这样：得分的文件6.2.0

query query = new PhraseQuery.Builder() 
         .add(new Term("country","russia")) 
         .setSlop(1) 
         .build();

基本上我的所有文件它们之中：

{ 
    "_id" : ObjectId("586b723b4b9a835db416fa26"), 
    "name" : "test", 
    "countries" : { 
     "country" : [ 
      { 
       "name" : "russia" 
      }, 
      { 
       "name" : "USA china" 
      } 
     ] 
    } 
} 
{ 
    "_id" : ObjectId("586b73f24b9a835fefb10ca5"), 
    "name" : "nitika jain", 
    "countries" : { 
     "country" : [ 
      { 
       "name" : "russia and denmrk" 
      }, 
      { 
       "name" : "USA china" 
      } 
     ] 
    } 
} 
{ 
    "_id" : ObjectId("586b744f4b9a835fefb10ca7"), 
    "name" : "arjun", 
    "countries" : { 
     "country" : [ 
      { 
       "name" : "russia pakistan" 
      }, 
      { 
       "name" : "india iraq" 
      } 
     ] 
    } 
}

我想其中有一个文件只有russia。理想情况下，应该是一个得分最高，而是我得到类似"Found 3 hits."

所有3个结果是同样打进。我怎样才能得到文件只有russia得分最高？

在短语查询中，缺省值为零，需要精确匹配。这意味着如果你以这种方式修改你的查询：

query query = new PhraseQuery.Builder() 
         .add(new Term("country","russia")) 
         .build();

你会得到你要找的。

其实它的工作，如果在索引时我将字段保留为stringFeild而不是文本字段，并进行普通查询而不是短语查询，但我需要该字段为TextFeild。 –
