How to use iNaturalist's Search URLs - wiki part 1 of 2

@lera

how would I filter for records that are missing their observation date?

The same is true for missing location, come to think of it, but missing date seems to be more common.

The same questions were asked here:
https://forum.inaturalist.org/t/searching-obs-with-no-date/5118
https://forum.inaturalist.org/t/find-exclude-observations-without-a-location/3571/

I don’t know of a way to find observaitons missing dates or locations, or those that have a placeholder, by using search filters on the website. I don’t think it is possible.
