According to http://build.fhir.org/search.html#table the data type 'Range' should map to search parameters of type 'quantity'.

However, the RiskAssessment-prediction search parameter has an expression like "RiskAssessment.prediction.probability" while this element can be either a decimal or a Range.

Possible resolutions to this issue include:

A. Updating the search summary table at 3.1.1.9 to mention that a Range can be mapped to a search parameter of type number; or

B. Updating the search parameter expression to only select this element when its of type decimal (e.g.

RiskAssessment.prediction.probability as decimal)
