# Delete Vector Index

> Delete an existing vector similarity search index.

This endpoint removes the specified index from the database. Important considerations:

* Deletion is permanent and cannot be undone
* Underlying vector data remains intact
* Queries will fall back to sequential scan
* Running queries during deletion may be slower
* Use run\_with\_orchestration=True for large indices to prevent timeouts
* Consider index dependencies before deletion

The operation returns immediately but cleanup may continue in background.
