In the Condition resource,
abatement-age search parameter is a quantity type, but the expression
Condition.abatement.as(Age) | Condition.abatement.as(Range) | Condition.abatement.as(Age) indicates that the value could be a range.
I couldn't find any information about how the search should be handled in the quantity search param section (http://hl7.org/fhir/search.html#quantity) so I want to confirm the behavior to make.
If there is a document with abatement that has Range with low = 5 and high = 10, then if a search comes in with ?abatement-age=8 (for the sake of simplicity, assuming that the system and code would match), what would be the result? Since prefix is not specified, it's implicitly set to EQ but I am not sure if it should match because 8 is within the range or it shouldn't match because technically 8 does not equal to range of 5 to 10. What about other prefixes such as less than and greater than and what not?
Also, is the expression correct that it repeats the as(Age) twice?
