elasticsearch - Elasticsearch 中的匹配短语查询中的单个单词是否有字符限制？

Question

Elasticsearch 相当新，所以可能不得不忍受我，我遇到了一个问题，如果我使用 20 个字符或更少的字符搜索文档，文档会出现，但是查询中同一个单词中的任何更多字符，我没有结果:

使用“苯氧甲基青霉素”没有任何文件。

使用 'phenoxymethylpenicil' 带回文件。

这是我尝试使用的查询:

{
    "match_phrase": {
        "genericNames.name": {
        "query": "phenoxymethylpenicillin",
        "slop": 15,
        "zero_terms_query": "NONE",
        "boost": 1.0
        }
    }
}

这是完整的查询: https://pastebin.com/DEJvP2uS
就像我说的那样，我对此还很陌生，这可能是没有在正确的区域中寻找的一点。
所以我的问题是，哪些可能的区域会导致这种情况，为什么？
谢谢!
编辑:
提供了来自样本数据的文档之一的摘录。我不能展示很多，因为很多都是敏感的，幸运的是我可以分享样本数据中的名称。这是来自我试图搜索的数据:

"genericNames":[
{
    "nameType":1,
    "name":"Phenoxymethylpenicillin 250mg tablets",
    "nameChangeCode":"0000",
    "nameBasisCode":"0001",
    "nameTypeDescription":"Name",
    "startDate":"1948-01-01T00:00:00.000000+0000",
    "endDate":"3456-02-01T00:00:00.000000+0000"
},
{
    "nameType":5,
    "name":"Penicillin V 250mg tablets",
    "nameTypeDescription":"Alternative Name 3",
    "startDate":"1948-01-01T00:00:00.000000+0000",
    "endDate":"3456-02-01T00:00:00.000000+0000"
}
],

我还提供了索引映射，因为它可能会提供额外的信息:

这一定是由于您的 genericNames.name 上的自定义分析器造成的。字段，您有不同的自定义分析器，您使用的索引时间是autocomplete_index和搜索时间autocomplete_search分析器，但问题中没有提供这些分析器的定义，只有mapping部分提供。
请提供 _setting 的输出索引上的 API，请参阅 https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-settings.html了解更多信息。
您需要检查为 phenoxymethylpenicillin 生成的 token 使用 analyze API两者都适用 autocomplete_index和 autocomplete_search分析器，您会注意到差异。
