【问题描述】：
我有一个仅适用于关键字类型的查询，但我不知道为什么。
但是，如果我使用 Match 查询和模糊参数，我可以使它与文本类型一起使用。
为什么会这样？
请参阅下面的查询
（工作查询应该返回 Eddie 的文档。）
1) 模糊查询文本类型 -> 不工作
GET kibana_sample_data_ecommerce/_search
{
"query": {
"fuzzy": {
"customer_first_name": {
"value": "Eddi",
"fuzziness": "AUTO"
}
}
}
}
2) 模糊查询关键字类型 - 工作
GET kibana_sample_data_ecommerce/_search
{
"query": {
"fuzzy": {
"customer_first_name.keyword": {
"value": "Eddi",
"fuzziness": "AUTO"
}
}
}
}
3) MATCH QUERY + FUZINESS -> WORKING
GET kibana_sample_data_ecommerce/_search
{
"query": {
"match": {
"customer_first_name.keyword": {
"query": "Eddi",
"fuzziness": "Auto"
}
}
}
}

【问题讨论】：
-
您是否有机会使用自定义分析器？介意发布您的索引设置吗？
-
是个好问题，但不，它是标准分析器
-
是否有其他匹配被返回或没有？
-
抱歉，这是我最后的想法。正如你所说，它可能是相关的，我认为值得研究这个方向。

我相信我发现了@tomslabbaert，这是一个棘手的问题。我使用了解释 API。并注意到，当模糊搜索文本时，我的文本被分析并且搜索找到“eddie”但我的查询是“Eddi”，因此到 eddie 的编辑距离是 2。1 用于小写 E，2 用于添加“e “ 在末尾。这是因为 Fuzzy Query 是术语级别的查询，因此不会对查询进行分析。如果我将查询小写，我会得到结果，因为 eddi -> eddie 正好是 1 个编辑距离。我想我明白了
