- **Deferred/Promise**: Async operations

### Index Alias Strategy

Zero-downtime index updates using dual aliases:

```
Index Naming: {baseIndex}.{timestamp}
Example:      my-suggest.20250123120000

Aliases:
├── Search Alias: {baseIndex}          (read operations)
└── Update Alias: {baseIndex}.update   (write operations)
```
