`DELETE /collections/{collection_name}/index/{field_name}`

Delete field index for collection

## Path parameters

- `collection_name` string, required
- `field_name` string, required

## Query parameters

- `wait` boolean
- `ordering` 'weak' | 'medium' | 'strong' — Defines write ordering guarantees for collection operations * `weak` - write operations may be reordered, works faster, default * `medium` - write operations go through dynamically selected leader, may be inconsistent for a short period of time in case of leader change * `strong` - Write operations go through the permanent leader, consistent, but may be unavailable if leader is down
- `timeout` integer

## Response `200`
