mapping——动态模板

Elasticsearch默认给字符类型为text和keyword的混合类型

1         "type": "text",
2             "fields": {
3               "keyword": {
4                 "type": "keyword",
5                 "ignore_above": 256
6               }
7             }

 

实际业务中，不是所有数据字段都需要进行分词的，可以将这部分数据字段的类型设置为keyword类型，需要分词的字段设置为text类型，进行分词。
