搜索弹性搜索中的名称和特殊字符

Question

我在某些名字中搜索名称，它有特殊字符（＆amp;，（），'）。     我的索引映射看起来像这样

{
    "settings": {
        "index": {
            "analysis": {
                "analyzer": {
                    "analyzer_startswith": {
                        "tokenizer": "keyword",
                        "filter": "lowercase"
                    }
                }
            }
        }
    },

  "mappings": {
        "doc": {
            "properties": {
                "namefeild": {
                    "search_analyzer": "analyzer_startswith",
                    "analyzer": "analyzer_startswith",
                    "type": "string"
                }
            }
        }
    }

我想搜索名称'你＆amp;我'。

{"query":{"bool":{"must":[{"match_phrase_prefix":{"namefeild":"you & me"}}}]}},"from":0,"size":100}

这时我搜索姓名直到'你＆amp;'我得到结果后，我得到结果null。     请帮帮我。

Answer 1

对我而言，＃34;你和＆＃34;和＆＃34;你＆amp;我＆＃34;

如果这仍然不适合您，请发布返回null结果的确切查询

PUT sf

    "settings": {
        "index": {
            "analysis": {
                "analyzer": {
                    "analyzer_startswith": {
                        "tokenizer": "keyword",
                        "filter": "lowercase"
                    }
                }
            }
        }
    },

  "mappings": {
        "doc": {
            "properties": {

                }
            }
