CodeSystemDisplayDefinition
  missing http://hl7.org/fhir/search-modifier-code Missing The search parameter returns resources that have a value or not.
  exact http://hl7.org/fhir/search-modifier-code Exact The search parameter returns resources that have a value that exactly matches the supplied parameter (the whole string, including casing and accents).
  contains http://hl7.org/fhir/search-modifier-code Contains The search parameter returns resources that include the supplied parameter value anywhere within the field being searched.
  not http://hl7.org/fhir/search-modifier-code Not The search parameter returns resources that do not contain a match.
  text http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code Below The search parameter tests whether the value in a resource is subsumed by the specified value (is-a, or hierarchical relationships).
  above http://hl7.org/fhir/search-modifier-code Above The search parameter tests whether the value in a resource subsumes the specified value (is-a, or hierarchical relationships).
  type http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code Identifier The search parameter applies to the identifier on the resource, not the reference.
  of-type http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code 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 http://hl7.org/fhir/search-modifier-code Iterate The search parameter indicates an inclusion directive (_include, _revinclude) that is applied to an included resource instead of the matching resource.

Explanation of the columns that may appear on this page:

Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
