elasticsearch - 同义词 token 过滤器

Question

我用同义词标记过滤器创建了一个测试索引

 PUT /synonyms-index
{

"settings": {

"analysis": {

"filter": {

"my_synonym_filter": {

"type": "synonym",

"synonyms": [

"shares","equity","stock"

]

}

},

"analyzer": {

"my_synonyms": {

"tokenizer": "standard",

"filter": [

"lowercase",

"my_synonym_filter"

]

}

}

}

}

}

然后我分析了API，

post synonyms-index/_analyze
{
"analyzer":"my_synonyms",
"text":"equity awesome"
}

我收到以下响应，以查看什么代币进入了反向索引，并且我期望按照同义词规则需要添加“股票”和“股票”，但事实并非如此。我在这里想念什么吗？

{
  "tokens": [
    {
      "token": "equity",
      "start_offset": 0,
      "end_offset": 6,
      "type": "<ALPHANUM>",
      "position": 0
    },
    {
      "token": "awesome",
      "start_offset": 7,
      "end_offset": 14,
      "type": "<ALPHANUM>",
      "position": 1
    }
  ]
}

JSON是常见的陷阱，

我们需要将其设置为(将所有内容都用双引号引起来，这构成一个规则并且遵循简单的扩展。)

"synonyms": [ "shares,equity,stock" ]

而不是

"synonyms": [

"shares","equity","stock"

]
