Find/Exclude observations without a location?

OK, weird twist on place exclusion: While searching through casual, I know how to exclude humans, pets, potted plants. and records without photos. If I also want to exclude ones without any location given, what is the proper exclusion term? These might not work: place_id=null or not_in_place=true (heh)

Then, I might as well also ask what the term is for excluding ones with no observation date. Thanks for advice!

Hm reading back over my post, it’s confusingly written. To be clear I want to search for observations that definitively do have a location, and exclude the ones without a location. These might not work for that: place_id=any or not_in_place=false

But since others may even specifically want to search for records without place or without date to help people get those particular orphaned observations in shape, I’ll leave the prior unclear post as an implied question about that too.

I took a stab at rewriting the topic title that I had thunk up. Feel free to change again. :)
