对于Elastic Search来说还算是新手，所以可能要面对我。我遇到一个问题，如果我使用20个或更少的字符来搜索文档，则会显示该文档，但是查询中同一单词中的任何其他字符，我没有结果：
这是我要使用的查询：
{
"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，我还很陌生，这可能是因为您没有寻找正确的区域。
所以我的问题是，什么可能的区域会导致这种情况，为什么？
谢谢！
编辑：提供的是从样本数据中的一个文档中提取的内容。由于它很敏感，因此我不能显示很多，幸好我可以共享示例数据中的名称。这来自我要搜索的数据：
"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，因为它可能会提供其他信息：

这一定是由于您在genericNames.name字段中使用的自定义分析器，您有不同的自定义分析器，正在使用的索引时间autocomplete_index和搜索时间autocomplete_search分析器而发生的，但问题中未提供这些分析器的定义，仅mapping提供了一部分。
请_setting在您的索引上提供API的输出，有关更多信息，请参阅https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-settings.html。
您需要检查生成的令牌phenoxymethylpenicillin使用分析API两个autocomplete_index和autocomplete_search分析，你会发现其中的差别。
