Create Search Index Aliases
- concept
A Search index alias lets you run a Search query against a Search index without using the original Search index name.
You can also use a Search index alias to run a Search query across multiple buckets, scopes, or Search indexes. The Search Service runs the Search query on each Search index in the alias, and returns a merged set of results.
Search index aliases are useful when you need to update an existing Search index.
For example, say you had a Search index, old-index
, and an alias, my-alias
.
If you wanted to make updates to old-index
, you could add it to the alias my-alias
.
If you created a clone of old-index
, then made your updates, you could replace old-index
in the alias my-alias
.
Using a Search index alias lets you edit old-index
without any downtime.
