我有一个仅适用于关键字类型的查询，我不知道为什么。
但是，如果我使用匹配查询和模糊参数，则可以使其与文本类型一起使用。
为什么会这样？
请参见下面的查询
（正在运行的查询应返回Eddie的文档。）
1）模糊查询文本类型->不起作用
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）匹配查询+ FUZINESS->工作
GET kibana_sample_data_ecommerce/_search
{
"query": {
"match": {
"customer_first_name.keyword": {
"query": "Eddi",
"fuzziness": "Auto"
}
}
}
}

答案 0 :(得分：0)
模糊查询是术语级别查询。这意味着查询不会被分析。
为什么查询1）失败
如果您查询“ Eddi”，它将与分析文本进行比较，在这种情况下为“ eddie”。
从“埃迪”到“埃迪”，它是2个编辑距离。
因此，查询不会成功，因为长度在3到5之间的词的最大编辑距离是1（使用“模糊性：自动”配置）
为什么查询2）成功
另一方面，如果您使用关键字，则关键字将被存储而不进行分析。因此。埃迪（Eddi）与埃迪（Eddie）的编辑距离为1。
