elasticsearch创建索引,elasticsearch自动创建索引

简述

elasticsearch 创建索引时通常需要配置mapping。mapping的含义类似于关系数据库中的表结构。但mapping更加灵活。

创建

以下实例是创建索引：my-index-000001，并加入dynamic_templates。
地址
http://localhost:9400/my-index-000001
方式
put
端口
http 端口
模板内容

{ "mappings": { "_default_": { "dynamic_templates": [ { "string_fields": { "match": "*", "match_mapping_type": "string", "mapping": { "analyzer": "ik_max_word", "fields": { "raw": { "ignore_above": 2000, "type": "keyword" } }, "index": "true", "omit_norms": true, "type": "text" } } } ], "properties": { "amount": { "type": "double" } } } }} curl 方式 curl --location --request PUT 'http://localhost:9400/my-index-000001' --header 'Content-Type: application/json' --data-raw '{ "mappings": { "_default_": { "dynamic_templates": [ { "string_fields": { "match": "*", "match_mapping_type": "string", "mapping": { "analyzer": "ik_max_word", "fields": { "raw": { "ignore_above": 2000, "type": "keyword" } }, "index": "true", "omit_norms": true, "type": "text" } } } ], "properties": { "contract_amount": { "type": "double" } } } }}' 总结

上面的模板中配置了 amount 为double 类型。分词器：ik_max_word，查询不分词的属性：raw
