elasticsearch - 我想使用过滤器进行搜索，该过滤器排除与条件或其他条件不匹配的结果：

问题描述

如果我像这样给出它，它的给出结果是期望 { "track_total_hits": true, "query": { "bool": { "must": [ { "bool": { "should": [ { "simple_query_string": { “字段”：[“GECORRIGEERDETOEVOEGING”]，“查询”：“ {uer} ”，“analyze_wildcard”：“true”，“default_operator”：“AND”}}]，“minimum_should_match”：1}}]}}， “_source”：[“GECORRIGEERDETOEVOEGING”，“INLEGDATUM”]，“大小”：30，“来自”：0 }

但是如果我这样给我就会出错

{
  "track_total_hits": true,
  "query": {
    "bool": {
      "must": [
        {
          "bool": {
            "should": [
              {
                "simple_query_string": {
                  "fields": [
                    "GECORRIGEERDETOEVOEGING"
                  ],
                  "query": "*{uer}*",
                  "analyze_wildcard": "true",
                  "default_operator": "AND"
                }
              },
              {
                "query_string": {
                  "default_field": "GECORRIGEERDETOEVOEGING.keyword",

                  "analyze_wildcard": "true",
                  "default_operator": "AND"
                }
              }
            ],
            "minimum_should_match": 1
          }
        }
      ]
    }
  },
  "_source": [
    "GECORRIGEERDETOEVOEGING",
    "INLEGDATUM"
  ],
  "size": 30,
  "from": 0
}

错误：

        "shard" : 0,

解决方案

当存在查询字符串的一部分并且需要被视为普通字符时，您必须转义 lucene 保留字符。所以在字符串中"*{uer}*"你必须逃避{和}。

{
  "track_total_hits": true,
  "query": {
    "bool": {
      "must": [
        {
          "bool": {
            "should": [
              {
                "simple_query_string": {
                  "fields": [
                    "GECORRIGEERDETOEVOEGING"
                  ],
                  "query": "*\\{uer\\}*",
                  "analyze_wildcard": "true",
                  "default_operator": "AND"
                }
              },
              {
                "query_string": {
                  "default_field": "GECORRIGEERDETOEVOEGING.keyword",
                  "query": "*{uer}*",
                  "analyze_wildcard": "true",
                  "default_operator": "AND"
                }
              }
            ],
            "minimum_should_match": 1
          }
        }
      ]
    }
  },
  "_source": [
    "GECORRIGEERDETOEVOEGING",
    "INLEGDATUM"
  ],
  "size": 30,
  "from": 0
}
