In creating my HAPI server, I'm trying to discover if there is a way that I can have a resource structure aware search entry point that just handles search parameters in a dynamic way, rather than having to change my method signature for @Search operations. I can see that there is a way to express allowUnknownParams=true to tell the URL parser to allow unknown parameters, so that seems like a good starting point. What I'm wondering is if there is code I can reuse in the Server to parse the URL parameters given in search.

You can get the unknown parameters from either the RequestDetails or the HttpServletRequest.
Jens Villadsen (Mar 11 2019 at 14:20):
There are loads of code snippets out there that parses HttpServletRequests
Keith Boone (Mar 11 2019 at 14:22):
Yeah, I get that (I've been using HttpServletRequest all the time for context management). What I want to know is more about how HAPI converts request paramters to TokenParam, StringAndListParam, et cetera. I'm certain HAPI already does this, and I can certainly find the code that does it. What I'm asking is if there's some code that's worthy of reuse in the server to attempt this with, or should just I start from scratch.

They are unknown parameters - so how would you know how to differentiate between them?

Is there any way to search Patients that have not been discharged? I can't figure out how to filter by Encounter.diagnosis.use parameter

@Grahame Grieve ^ any tips ?
Grahame Grieve (Jan 21 2020 at 10:51):
it doesn't look like the spec defines a way to do this
Keith Boone (Jan 21 2020 at 14:31):
Wouldn’t that be patients having an encounter that is both in-patient (Encounter.class) and in-progress (Encounter.status)?

is there an easy way to list search parameters supported by HAPI FHIR JPA Server ? asked here https://chat.fhir.org/#narrow/stream/179166-implementers/topic/Implementing.20.20_sort/near/186255988

Is there a way to search/filter Encounter only related to Admitting Diagnosis ? I have tried diagnosis.use=DD, diagnosis:use=DDbut can't figure it out

Hi,
Maybe a bit odd question:
Can HAPI only return a set of attributes of the requested resources? For example I want the list of cities of all my Patients on the HAPI FHIR server. I looked it up on the FHIR Search references but didn't find something that can do that. Maybe it's something you should process on the client side?
