Filters

Code Description operator Value
concept Filter that includes concepts based on their logical definition. e.g. [concept] [is-a] [x] - include all concepts with an is-a relationship to concept x, or [concept] [in] [x]- include all concepts in the reference set identified by concept x is-a in A SNOMED CT code
expression The result of the filter is the result of executing the given SNOMED CT Expression Constraint = A SNOMED CT ECL expression (see http://snomed.org/ecl)
expressions Whether post-coordinated expressions are included in the value set = true or false
