Searching for Data
This section contains information about methods for searching for data in the CDR.
In addition to implementing most of the FHIR Search specification, Smile CDR implements the following extensions:
_source
An additional search parameter called _source
can be used to search for resources based on information about the system or request that created the resource. See Storing Source Information.
%now
Date searches can be performed relative to "now" using the %now
parameter value. For example, to search for Procedures with a date later than now, you can search for /Procedure?date=ge%now
.
Note the '%' would need to be URL escaped so the actual URL will be /Procedure?date=ge%25now
The way this works is Smile substitutes %now
with the current date and time in the standard FHIR format yyyy-MM-ddTHH:mm:ss
before submitting it to the FHIR Storage module.
Smile CDR does not currently support the _contained
and _containedType
FHIR Search parameters.
