===== Add a time-based alias
|
|
|
|
The following request creates an alias, `2030`,
|
|
for the `logs_20302801` index.
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
PUT /logs_20302801/_alias/2030

===== Add a user-based alias

with a mapping for the `user_id` field:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
PUT /users
|
|
{
|
|
"mappings" : {
|
|
"properties" : {
|
|
"user_id" : {"type" : "integer"}
|
|
}
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
|
|
Then add the index alias for a specific user, `user_12`:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
PUT /users/_alias/user_12
|
|
{
|
|
"routing" : "12",
|
|
"filter" : {
|
|
"term" : {
|
|
"user_id" : 12
|
|
}
|
|
}
|
|
}
