我们正在运行 Elasticsearch 1.7(计划很快升级),我正在尝试使用分析 API 来了解不同分析器的作用,但从 elasticsearch 呈现的结果不是我所期望的。
如果我对我们的 elasticsearch 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
}
]
}
这对我来说没有意义。我正在使用停止分析器,为什么结果中有“and”和“the”这两个词?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,结果将不再包含“and”和“the”,而且看起来更符合预期。
这是因为我们使用的是 1.7 还是我们的 Elasticsearch 设置中的某些东西导致了这个问题?
编辑: 我在 chrome 中使用 Sense 插件进行查询,该插件不支持带有请求正文的 GET,因此它将请求更改为 POST。Elastic Analyze API 1.7 似乎不支持 POST 请求 :( 如果我像这样更改查询 GET _analyze?analyzer=stop&text=THIS+is+a+test&pretty 它可以工作
