Operation

# title
Given a set of code-value properties, return one or more possible matching codes.

# description
This is an immature part of the [FHIR Specification](https://hl7.org/fhir/R4/codesystem-operation-find-matches.html), and only initial support is provided, and both the `exact` and `compositional` parameters will have no impact on the output. The implementation effectively behaves aligned with `exact=true` and `compositional=false`, and as such is aimed at machine/automated use rather than human/interactive use.

# parameter[].documentation
Whether post-coordinated expressions are allowed as matches.

# parameter[].documentation
`property.code` and `property.value` pairs; `property.subproperty` is not yet supported.

# parameter[].documentation
The code system in which to search for matches.
