我可以在λ curl -XGET -u elastic:elasticpassword http://192.168.1.71:9200/test/mytype/_mapping?pretty { "test" : { "mappings" : { "mytype" : { "properties" : { "age" : { "type" : "long" }, "name" : { "type" : "text", "fields" : { "keyword" : { "type" : "keyword", "ignore_above" : 256 } } }, 字段找到，但不能在age字段找到。为什么？

name

Answer 1

问题是您的名称字段默认使用标准分析器进行分析，该分析器会对字段进行小写。您可以搜索paul或使用name.keyword在Paul字段中搜索。
