Expansion based on Search Modifier Code v5.0.0 (CodeSystem)

Code	System	Display	Definition
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
