Question

我的查询无效。我认为搜索的值包含＆amp; （＆符号）符号。我在谈论以下问题。

GET "path"_search
{

  "from": 0,
  "size": 10000,
  "query": {
    "query_string": {
      "query": "(Department_3037.Department_3037_analyzed:*P&C*)"
    }    
  }
}

为什么这个查询不起作用以及如何克服这个问题，或者我需要查询包含＆amp;的字符串喜欢（p＆amp; c），l＆amp; t等... 让我知道如何解决这个问题。谢谢。

由于您要搜索的字段为analyzed。如果该字段包含文字(Department_3037.Department_3037_analyzed:*P&C*)，则会将其标记为：Department_3037，Department_3037_analyzed，P，C。

你可以使用：

curl -XGET "http://localhost:9200/_analyze?tokenizer=standard" -d "(Department_3037.Department_3037_analyzed:*P&C*)"

您将获得如下令牌：

{"tokens":[{"token":"Department_3037","start_offset":1,"end_offset":16,"type":"<ALPHANUM>","position":1},

{"token":"Department_3037_analyzed","start_offset":17,"end_offset":41,"type":"<ALPHANUM>","position":2},

{"token":"P","start_offset":43,"end_offset":44,"type":"<ALPHANUM>","position":3},

{"token":"C","start_offset":45,"end_offset":46,"type":"<ALPHANUM>","position":4}]}.

如果要检索文档，则必须转义特殊字符：

{
"query": {
   "query_string": {
      "default_field": "name",
      "query": "\\(Department_3037\\.Department_3037_analyzed\\:\\*P\\&C\\*\\)"
    }
   }
 }

希望它有所帮助。

弹性搜索：像查询不在字符串中包含＆amp;（和号）？
