Topic: Reverse chaining with _filter
Ivan Dubrov (Aug 04 2018 at 04:06):
Is it possible to use reverse chaining ("_has:Observation:patient:code") using "_filter" syntax?
Forward chaining seems to be possible in "_filter", for example, "_filter= subject.name eq peter". However, I don't see how can I do a reverse chaining?

I haven't updated _filter since we defined reverse chaining

Now that Gforge #17489 is applied, shouldn't reverse chaining work "out of the box"? Is there any reason why I should not be able to use the same _has syntax as usual in a filter expression?

cause adding it to the grammar isn't the same as adding it the reference servers

Fair point :grinning:
