I dont know of a way to save searches by URL parameters. The searches are generally POST requests to the
/api/external/v1/search/CaseSearchEverything
endpoint, though I’ve noticed exceptions when linked from the Dashboards view. Are you looking for a programatic way to apply the left panel filters? I’ve made POST requests in python to get the data from searches, but that comes back as json and not a link you can share with people.

Thanks Josh, for now I'm looking for "quick" way to apply the filters on the left, on top of the 4 search parameters.

As it is, I have to manually configure these every time I want to use them... and presently this is for about 25 searches each, every day, for 7 people.

this would be a great feature request. it is a pain to manually redo 25 searches. a quick win might be geasemonkey scripts that find the correct filters on the page and apply them

Yeah, I've got something like that hacked together now, but, it's going the way of an FR. Thanks Josh.
