Value Set Search Modifier Code

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

Code Display Definition
missing Missing The search parameter returns resources that have a value or not.
exact Exact The search parameter returns resources that have a value that exactly matches the supplied parameter (the whole string, including casing and accents).
contains Contains The search parameter returns resources that include the supplied parameter value anywhere within the field being searched.
not Not The search parameter returns resources that do not contain a match.
text Text The search parameter is processed as a string that searches text associated with the code/value - either CodeableConcept.text, Coding.display, Identifier.type.text, or Reference.display.
in In The search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the coding is in the specified value set.
not-in Not In The search parameter is a URI (relative or absolute) that identifies a value set, and the search parameter tests whether the coding is not in the specified value set.
below Below The search parameter tests whether the value in a resource is subsumed by the specified value (is-a, or hierarchical relationships).
above Above The search parameter tests whether the value in a resource subsumes the specified value (is-a, or hierarchical relationships).
type Type The search parameter only applies to the Resource Type specified as a modifier (e.g. the modifier is not actually :type, but :Patient etc.).
identifier Identifier The search parameter applies to the identifier on the resource, not the reference.
of-type Of Type The search parameter has the format system|code|value, where the system and code refer to an Identifier.type.coding.system and .code, and match if any of the type codes match. All 3 parts must be present.
code-text Code Text Tests whether the textual display value in a resource (e.g., CodeableConcept.text, Coding.display, or Reference.display) matches the supplied parameter value.
text-advanced Text Advanced Tests whether the value in a resource matches the supplied parameter value using advanced text handling that searches text associated with the code/value - e.g., CodeableConcept.text, Coding.display, or Identifier.type.text.
iterate Iterate The search parameter indicates an inclusion directive (_include, _revinclude) that is applied to an included resource instead of the matching resource.
