Topic: Usage of prefixes in comma separated values
Anand Mohan Tumuluri (Mar 10 2020 at 10:50):
We recently got a question around the usage of prefixes(ge,le,gt,lt,etc) in comma separated list of values intended for OR matching. (The original question was for composite parameter Observation.component-code-value-quantity to simultaneously search for systolic values greater than some value or diastolic value lesser than some value). To generalize, are servers expected to support prefixes when dealing with comma separated list of values?

The public FHIR test server supports it indeed.
http://test.fhir.org/r3/Observation?code=urn:iso:std:iso:11073:10101|150020&component-value-quantity=ge130,le30&_count=10

Servers aren't required to support much when it comes to query, but it's certainly valid FHIR.
