4.3.2.223.2 Content

This code system http://hl7.org/fhir/subscription-search-modifier defines the following codes:

Code	Display	Definition	Copy
=	=	Used to match a value according to FHIR Search rules (e.g., Patient/123, Encounter/2002).
eq	Equal	The value for the parameter in the resource is equal to the provided value.
ne	Not Equal	The value for the parameter in the resource is not equal to the provided value.
gt	Greater Than	The value for the parameter in the resource is greater than the provided value.
lt	Less Than	The value for the parameter in the resource is less than the provided value.
ge	Greater Than or Equal	The value for the parameter in the resource is greater or equal to the provided value.
le	Less Than or Equal	The value for the parameter in the resource is less or equal to the provided value.
sa	Starts After	The value for the parameter in the resource starts after the provided value.
eb	Ends Before	The value for the parameter in the resource ends before the provided value.
ap	Approximately	The value for the parameter in the resource is approximately the same to the provided value. Note that the recommended value for the approximation is 10% of the stated value (or for a date, 10% of the gap between now and the date), but systems may choose other values where appropriate.
above	Above	The search parameter is a concept with the form [system]|[code], and the search parameter tests whether the coding in a resource subsumes the specified search code.
below	Below	The search parameter is a concept with the form [system]|[code], and the search parameter tests whether the coding in a resource is subsumed by the specified search code.
in	In	The search parameter is a member of a Group or List, or the search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the value is present in the specified Group, List, or Value Set.
not-in	Not In	The search parameter is a member of a Group or List, or the search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the value is NOT present in the specified Group, List, or Value Set.
of-type	Of Type	The search parameter has the format system|code|value, where the system and code refer to a Identifier.type.coding.system and .code, and match if any of the type codes match. All 3 parts must be present.
