Hello all.
Typesense looks like a very interesting project, grats to the team here!

One small question from my side: Does typesense support facets with range?
For example counters for documents with posted date (yesterday, three days ago, last week, all time).

Thanks in advance,
Stelios

Thanks Stelios!

Typesense does not support facets with ranges like you describe, for timestamps. But we’re working on adding support ranges with numbers: https://github.com/typesense/typesense/issues/386

One more question if you know, while using the paging feature I can see that the request does not contain any type of timestamp or versioning for prohibiting any new/modified documents after the first page on the index

Is this being handled somehow or any possible duplicates due to the score changing for example should be handled in the front client?

I’ll defer to Kishore Nallan to speak to this ^

If you are doing updates during pagination, then yes, the next page could have duplicates because of the order changing. This is tricky to handle generically, so it must be handled on the frontend. Let me know if you have any suggestions on supporting this natively.
