Elasticsearch shingle 令牌过滤器不起作用

Question

我正在本地 1.7.5 elasticsearch 安装上尝试这个

http://localhost:9200/_analyze?filter=shingle&tokenizer=keyword&text=alkis stack

我看到了这个

{
   "tokens":[
      {
         "token":"alkis stack",
         "start_offset":0,
         "end_offset":11,
         "type":"word",
         "position":1
      }
   ]
}

我希望看到这样的东西

{
   "tokens":[
      {
         "token":"alkis stack",
         "start_offset":0,
         "end_offset":11,
         "type":"word",
         "position":1
      },
      {
         "token":"stack alkis",
         "start_offset":0,
         "end_offset":11,
         "type":"word",
         "position":1
      }
   ]
}

我是不是漏掉了什么？

        ],
        "type": "custom",
        "tokenizer": "keyword"
      }
    }
  }
}

我正在尝试这样测试

Answer 1

在 ES 中 两个单独的字段 中索引名字和姓氏，就像在数据库中一样。可以分析作为查询收到的文本（例如，match 执行此操作，query_string 执行此操作）。还有一些方法可以使用搜索字符串中的所有术语同时搜索这两个字段。我认为您一次性使用单个名称使用例过于复杂，并在索引时创建名称排列。
