带有'>'的elasticsearch通配符字符串搜索查询

Question

我有映射为 'not_analyzed' 的字符串字段。每个字符串都有 '>' 符号，需要用它找到一些字符串。

string e.g)

one>two>tree>four>...

通过以下查询，我可以获得预期的结果。

"query": { "wildcard": { "activityseq": { "value": "one*" } } }

但是当在值中添加'>'时，它不是。

"query": { "wildcard": { "activityseq": { "value": "one>*" } } }

或

"query": { "wildcard": { "activityseq": { "value": "one>*" } } }

有什么想法吗？

查询+结果

1.

"query": { "wildcard": { "activityseq": { "value": "maketicket*" } } }

result : data as I expect

2.

"query": { "wildcard": { "activityseq": { "value": "maketicket>*" } } }

结果

"hits": { "total": 0, "max_score": null, "hits": [] }

3.

"query": { "wildcard": { "activityseq.raw": { "value": "maketicket*" } } }

结果

"hits": { "total": 0, "max_score": null, "hits": [] }

4.

"query": { "wildcard": { "activityseq": { "value": "maketicket>*" } } }

结果

"caused_by": { "type": "json_parse_exception", "reason": "Unrecognized character escape '>' (code 62)\n at [Source: [B@61201912; line: 5, column: 37]" }

Answer 1

您的查询需要看起来像这样才能正常工作，即您需要匹配 seqstring.raw 子字段，因为那是 not_analyzed

{
  "query": {
    "wildcard": {
      "seqstring.raw": {
        "value": "one>*"
      }
    }
  }
}
