Values of `__hf_index_id` in DuckDB indexes are not in the right order
For example the first item in de C4 dataset is supposed to be

```
Beginners BBQ Class Taking Place in Missoula!...
```

This is also the first example when querying the DuckDB index, but it has `__hf_index_id == 1000`

```python
con.sql("select * from data limit 5;")
```

```

This would show the wrong row idx when clicking on the example after search (which times out atm though)

Not a big deal for now imo
