I'd assume searches for the majority might be very "bursty", and while they may indeed spend most of their time in Facebook, Tiktok etc. when planning a vacation, searching for stuff to purchase or looking up recipes to try and the like, they'd issue a number of queries to narrow down into their area of interest which would blow past your estimate of 10 queries/day. There are also a fair number of queries that are just "Facebook", "<name of famous newspaper>" etc. which would also probably count towards some of the quota; it'd be great if some sort of caching could be implemented for these.
