别名不能重复,也不能喝索引名称重复。(一个索引可以创建多个别名)
语法:
添加一个别名:
url:POST http://192.168.0.108:9200/_aliases/
参数:
{
"actions": [{
"add": {
"index": "yingshe",
"alias": "yingshealias"
}
}]
}
添加一个别名(多个索引):
两种写法
(1)
{
"actions": [{
"add": {
"indices":["test1","test2"]
"alias": "yingshealias"
}
}]
}
(2) 新写一个add
删除别名:
url:POST http://192.168.0.108:9200/_aliases/
参数:
{
"actions": [{
"remove": {
"index": "yingshe",
"alias": "yingshealias"
}
}]
}
1.过滤索引别名:
url:PUT
参数:http://192.168.0.108:9200/test1/
{
"mapping": {
"type1": {
"properties": {
"user": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
创建过滤别名:
url:POST http://192.168.0.108:9200/_aliases/
参数:
{
"actions": [{
"add": {
"index": "test1",
"alias": "alias2",
"filter": {
"term": {
"user": "kimchy"
}
