you will need to include time entries in the filter
as an example - to find objects updated today (May 3rd 2021) you can use this (in q or fq)
core.lastModified:[2021-05-03T00:00:00.000Z TO 2021-05-03T23:59:59.999Z]
Thanks! That seemed to work.
A quick follow up question: What's the difference between using q vs fq? In my testing, I haven't noticed a meaningful difference in the responses I get. When should I use one vs the other?
