Topic: Search for observations without focus
Paul Lynch (Jan 30 2019 at 20:21):
Is it possible to query for observations and limit the the results to ones which do not have Observation.focus set?
I can see that there is a "focus" search parameter for Observation, but I don't think the appending "focus=" (no value) to the query string is likely to work.

check the :exists modifier

@Paul Lynch bear in mind that not all servers support all modifiers.

@Michael Donnelly Thanks for the warning.
