Some entities imported via `search:import` are not indexed (missing records)

- Symfony version: `v6.2.7`
- Algolia Search Bundle version: `6.0.0`
- Algolia Client Version: N/A
- Language Version: `PHP 8.1.14 (cli)`

### Description

When importing entities with `search:import`, the logs display correct index counts, but when browsing the index, some are missing.

Here is the command output:
```
> bin/console search:import
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 500 / 500 App\Entity\MediaTranslation entities into quentin_media index
Indexed 160 / 160 App\Entity\MediaTranslation entities into quentin_media index
Done!
```

I'd then expect my index to contain `14 * 500 + 160 = 7160` items, but only `5216` exist:


But clearing the index and importing again yields another record count (+/-5%).

Here's my configuration:

```yaml
algolia_search:
prefix: '%algolia_search_prefix%'
indices:
- name: media
class: App\Entity\MediaTranslation
```

And here's the index settings file (created with `search:settings:backup`)

```json

"minWordSizefor2Typos": 8,

```

**What could prevent records from appearing in my index?**

Start with the `search:import` command and the Algolia Search Bundle configuration for `App\Entity\MediaTranslation`; compare the reported batch counts with the records in the Algolia dashboard while reviewing Symfony logs. Done means identifying why records are intermittently missing and preventing the import from completing with an incomplete index.
