`SearchIndexMigrator` converts search indexes between the SQLite (`.swsearch`)
and pgvector (PostgreSQL) backends. This is useful when moving from local
development to production, or when changing infrastructure.

```python
from signalwire.search import SearchIndexMigrator
```

> **Warning**
>
> Requires search dependencies and the pgvector backend package.
> Install with `pip install signalwire-sdk[search-all]`.
