[Misc] About Encounter Resource Search
inatam opened this issue · 6 comments
What we want to do
To search data of particular period of time even if resource lacks "period.end".
premise
Resource without period.end exists.
question
When we try to search data by "date", resources without "period.end" cannot be acquired.
Is there any way to search data of particular period of time and sort the data, even if resource lacks "period.end"?
Also, is it possible to search and sort data by "period.start" only, not by "date"?

Hi @inatam
We use elastic search for date searches, and based on our code it need a period.end.
You can search for period.start https://build.fhir.org/encounter-search.html#8.11.23
The FHIR specification details how open-ended periods are handled. Note the mention that "the lower or upper bound might not actually be specified" for a Period, and that "implicitly, a missing lower boundary is 'less than' any actual date. A missing upper boundary is 'greater than' any actual date." The date search logic should take this into consideration; the current behaviour is not compliant.
Hi @ElliotSilver, thanks for pointing that out. I added this to our backlog.
Best,

Hi @kcadette
Error response was returned by making the following request:
*My FWoA environment is version4.
It seems that the method you suggest is supported from version5.
Is there any way to do a similar search in version4?
There is a date search on Encounter resource in FHIR r4: https://www.hl7.org/fhir/encounter.html#search
Thank you.
