So you essentially have to budget your queries to make sure you have enough. Which is unproductive. The "simple queries" should already be cached aon the server and should not even count to the quota.
To clarify, there is no limit on Kagi. Searches are 1.5 cents per search (after those included with subscription) and you can do as many as you’d like. Or get an unlimited plan. A lot of things don’t cost a search (bangs, reloads etc..)
