If you no longer require a search index that is created for a data table, you can delete the search index.

Important
A canary index is a mechanism for dynamically modifying the schema of a search index. For more information, see Dynamically modify the schema of a search index. A canary index allows you to add, update, or remove index columns from a search index and modify the routing key and sorting method for a search index without business interruption. You do not need to delete the existing search index and create a new search index.
