Hi All, We have multiple fields with int[] type that are set to facet=True, problem is when we use facet, the response time takes around 4s but without facet it only takes 100ms, is there a way to optimize the facet?

You can try doing estimation of facets via the

facet_sample_percent

and

facet_sample_threshold

parameters.

read about it, but it will not return exact count, right?

Yes, it's a tradeoff between performance and speed. With

facet_sample_threshold

the counts will be accurate when small number of hits are found, but for larger results, estimation is done.

@Kishore Nallan from the documentation, it says facet sampling is disabled by default, will it be enabled by adding either of these 2

facet_sample_threshold

and

facet_sample_percent

?

Yes

sorry, just to confirm,

facet_sample_threshold

if I set this to

10

and I only return

15

per page with

found=1000

, will it apply sampling on facet?

Yes that should apply sampling.

@Kishore Nallan

facet_sample_threshold

didn't help, still experiencing slow response time due to facet (from array of integers), is there a way where it will improve by increasing resources i.e. RAM, CPU or DISK? I mean the processing of facet, is it on the CPU side or other?

It's CPU bound, so a larger machine will help. Are you using Typesense cloud or self hosting?

@Kishore Nallan cloud

Can you DM me your cluster ID and the exact query that you are trying? I can take a look and get back to you.

@Kishore Nallan for the cluster id, you're referring to the node or host id, right?
