主要知识点
- 索引CUD
一、创建索引的语法
PUT /my_index
{
"settings": { ... any settings ... },
"mappings": {
"type_one": { ... any mappings ... },
"type_two": { ... any mappings ... },
...
}
}
创建索引的示例
PUT /company
{
"settings":{
"number_of_shards":1,
"number_of_replicas":0
},
"mappings": {
"employee": {
"properties": {
"name":{
"type":"text"
}
}
}
}
}
二、修改索引
PUT /company/_settings
{
"number_of_replicas": 1
}
三、删除索引
DELETE /my_index
DELETE /index_one,index_two
DELETE /index_*
DELETE /_all
四、其他
elasticsearch.yml中把action.destructive_requires_name: true，这样设置后就不能直接用delete /_all把所有的索引删除，必须指定索引名才能删除
