i changed search to datamodel search(tstats) for speed up.
but, stats and tstats result are slightly different.
ex) tstats : 0.45500000000000007.
stats : 0.4549999999999999.
it is same data.
Thank you for your reply.
Could you please share your
tstats query with us ?
Usually if you're not getting the same results it could be that your
tstats is running on accelerated whereas stats is taking all data into consideration.
Another reason could be that your DM isn't using all the data because of the defined constraints make sure your DM's constraint is the same as the one you are using with stats search.
