Hi, I would like to know if there are any limitations when it comes to faceted float fields and the

stats

parameter (sum in particular). Sample use case: An

invoice

collection and a facet on the

invoice_total

- would it be possible to use the

stats

field to get the sum of all invoices (~20k documents) - and what are the trade-offs / limitations with this? I notice a parameter called

sampled

which is currently False - is this relevant?

You can indeed use facet_by on numeric fields like you've described. There are no limitations to this

Thanks
