NEURLFilterDataFormat seems to be incomplete

NEURLFilterDataFormat doc seems to be incomplete as it only covers one use case:
https://github.com/apple/pir-service-example/blob/main/Sources/PIRService/PIRService.docc/NEURLFilterDataFormat.md

It's unclear from the documentation how exactly will it work with full URLs and whether we should have full URLs in the database or whether it will work like Google Safebrowsing and check several possible URL parts.

The system filters all URL requests initiated with Webkit and URLSession APIs. During URL filtering, the system performs sub-URL generation to enumerate all possible sub-URLs for the URL in question. So it is similar to what is described for Google Safebrowsing.

@karulont sounds great!

Could you please tell me if there's relevant documentation that explains the rules for sub-URLs generation?

[karulont]

Unfortunately I do not believe there is any documentation for that currently.
