Searching for an Encounter based on time has a number of issues. #52
Description
timeDate can represent periods of time rather than discrete datetime values. Because they are used in Encounter periods, there are a number of related issues around the way in which searches should behave.
Any query for an Encounter which includes a time should return Encounters that only have dates recorded given that a date alone encompasses a range of times. For example, Encounter?date=2017-10-17T13:58 should return 4509 which has a start and end dates but no times. Those Encounters which only have a start date should be handled this way also.
Ref: https://www.hl7.org/fhir/search.html#date
The range of the value as defined above; e.g. For example, the date 2013-01-10 specifies all the time from 00:00 on 10-Jan 2013 to immediately before 00:00 on 11-Jan 2013
date=2017-10-17T13:59 should return 4129 which has a start time of 13:59. This works ok but it should also be returning Encounters such as 4139 that starts at 13:39 and finishes at 14:15.
