对于elastic search来说还很陌生，所以我可能不得不直言不讳，我遇到了一个问题，如果我搜索一个使用20个或更少字符的文档，该文档就会出现，但是在查询中，如果同一个词中有更多字符，我将得不到任何结果：
使用“苯氧甲基青霉素”不会带来任何文件。
使用“苯氧甲基青霉素”会带回文件。
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
}
}
}以下是完整查询：https://pastebin.com/dejvp2us
就像我说的，我对这方面还比较陌生，可能是找不到正确的地方。
所以我的问题是，什么可能的领域会导致这种情况，为什么？
谢谢！
编辑：提供的是从示例数据的一个文档中提取的内容。我不能显示很多，因为它是敏感的，幸运的是，我可以分享的样本数据的名称很多。这是我试图搜索的数据：
"genericNames":[
{
"nameType":1,
"name":"Phenoxymethylpenicillin 250mg tablets",
"nameChangeCode":"0000",
"nameBasisCode":"0001",

},

在上面提供的索引Map中，
genericNames是嵌套类型，因此需要使用嵌套查询添加一个工作示例，使用与上面提供的相同的索引数据以及搜索查询和搜索结果。
搜索查询：
搜索结果：
sy5wg1nm2#
这一定是由于您的计算机上有自定义分析器
genericNames.name字段，您有不同的自定义分析器，索引时间您正在使用的autocomplete_index和搜索时间autocomplete_search分析器，但这些分析器的定义并没有在问题中提供，只是mapping提供零件。请提供输出
_setting索引上的api，请参阅https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-settings.html 更多信息。您需要检查为生成的令牌
phenoxymethylpenicillin将分析api用于autocomplete_index以及autocomplete_search你会注意到其中的区别。
