1、创建索引
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 /my_index
{
”settings”: {
”number_of_shards”: 1,
”number_of_replicas”: 0
},
”mappings”: {
”my_type”: {
”properties”: {
”my_field”: {
”type”: “text”
}
}
}
}
}
2、修改索引
PUT /my_index/_settings
{
”number_of_replicas”: 1
}
3、删除索引
DELETE /my_index
DELETE /index_one,index_two
DELETE /index_*
DELETE /_all
可以设置下面的属性，使DELETE /_all 失效，必须指定索引名称，才可以删除。
elasticsearch.yml
action.destructive_requires_name: true
