Question

我们正在运行Elasticsearch 1.7（计划很快升级），我正在尝试使用Analyze API来了解不同分析器的功能，但弹性搜索的结果并不是我所期望的。

如果我对弹性搜索实例运行以下查询

GET _analyze
{
  "analyzer": "stop", 
  "text": "Extremely good food! We had the happiest waiter and the crowd's always flowing!"
}

我会得到这个结果

{
   "tokens": [
  {
     "token": "analyzer",
     "start_offset": 6,
     "end_offset": 14,
     "type": "<ALPHANUM>",
     "position": 1
  },
  {
     "token": "stop",
     "start_offset": 18,
     "end_offset": 22,
     "type": "<ALPHANUM>",
     "position": 2
  },
  {
     "token": "text",
     "start_offset": 30,
     "end_offset": 34,
     "type": "<ALPHANUM>",
     "position": 3
  },
  {
     "token": "extremely",
     "start_offset": 38,
     "end_offset": 47,
     "type": "<ALPHANUM>",
     "position": 4
  },
  {
     "token": "good",
     "start_offset": 48,
     "end_offset": 52,
     "type": "<ALPHANUM>",
     "position": 5
  },
  {
     "token": "food",
     "start_offset": 53,
     "end_offset": 57,
     "type": "<ALPHANUM>",
     "position": 6
  },
  {
     "token": "we",
     "start_offset": 59,
     "end_offset": 61,
     "type": "<ALPHANUM>",
     "position": 7
  },
  {
     "token": "had",
     "start_offset": 62,
     "end_offset": 65,
     "type": "<ALPHANUM>",
     "position": 8
  },
  {
     "token": "the",
     "start_offset": 66,
     "end_offset": 69,
     "type": "<ALPHANUM>",
     "position": 9
  },
  {
     "token": "happiest",
     "start_offset": 70,
     "end_offset": 78,
     "type": "<ALPHANUM>",
     "position": 10
  },
  {
     "token": "waiter",
     "start_offset": 79,
     "end_offset": 85,
     "type": "<ALPHANUM>",
     "position": 11
  },
  {
     "token": "and",
     "start_offset": 86,
     "end_offset": 89,
     "type": "<ALPHANUM>",
     "position": 12
  },
  {
     "token": "the",
     "start_offset": 90,
     "end_offset": 93,
     "type": "<ALPHANUM>",
     "position": 13
  },
  {
     "token": "crowd's",
     "start_offset": 94,
     "end_offset": 101,
     "type": "<ALPHANUM>",
     "position": 14
  },
  {
     "token": "always",
     "start_offset": 102,
     "end_offset": 108,
     "type": "<ALPHANUM>",
     "position": 15
  },
  {
     "token": "flowing",
     "start_offset": 109,
     "end_offset": 116,
     "type": "<ALPHANUM>",
     "position": 16
  }
   ]
}

对我来说没有意义。我正在使用停止分析器，为什么结果中的单词“和”和“the”？我试图将停止分析器更改为空白和标准，但我得到与上面完全相同的结果。它们之间没有区别。但是，如果我对Elasticsearch 5.x的实例运行完全相同的查询，结果不再包含“and”和“the”，它看起来更像预期。

这是因为我们使用1.7还是在我们的Elasticsearch设置中导致了这个问题呢？

修改我在chrome中使用Sense插件来执行我的查询，并且插件不支持请求正文的GET，因此它将请求更改为POST。 Elastic Analyze API 1.7似乎不支持POST请求:(如果我改变查询，就像这样GET _analyze？analyzer = stop＆amp; text = THIS + is + a + test＆amp; pretty it works

Answer 1

在1.x中，语法与2.x and 5.x不同。根据1.x documentation，您应该使用_analyze API，如下所示：

GET _analyze?analyzer=stop
{
  "text": "Extremely good food! We had the happiest waiter and the crowd's always flowing!"
}

Analyze API不适用于Elasticsearch 1.7
