Kagi does not support true time-based searches such as "Past four years", which in Google is simple &tbs=qdr:4, but I also don't seem to be able to create a lense for a period - even the pre-built 2020s lense, for launching from Orion.
In other words, in Orion, you create quick search short-cuts. In my case, g4 is "search using Google, limited to the last four years", which is "https://www.google.com/search?q=%s&tbs=qdr:y4"
I have Kagi equivalents for single units, because Kagi doesn't support multiples. e.g. "Kagi Year", shortcut "ky", is "https://kagi.com/search?q=%s&token=<mytoken>&dr=4"
And, of course, Kagi as my default, but using the lense shortcut isn't so convenient as this approach.
Meanwhile, I can get a lense URI, but it's for editing, not searching.
How do I create a lense and then call it from an Orion QuickSearch link?
Users could easily create Orion QuickSearch links for "Kagi search last three years."
