索引增删改

1、为什么我们要手动创建索引？

2、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"
								}
						}
				}
		}
}

3、修改索引


PUT /my_index/_settings
{
"number_of_replicas": 1
}

4、删除索引

DELETE /my_index DELETE /index_one,index_two DELETE /index_* DELETE /_all
