CodeDisplayDefinition
missingMissingThe search parameter returns resources that have a value or not.
exactExactThe search parameter returns resources that have a value that exactly matches the supplied parameter (the whole string, including casing and accents).
containsContainsThe search parameter returns resources that include the supplied parameter value anywhere within the field being searched.
notNotThe search parameter returns resources that do not contain a match.
textTextThe search parameter is processed as a string that searches text associated with the code/value - either CodeableConcept.text, Coding.display, or Identifier.type.text.
inInThe 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-inNot InThe 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.
belowBelowThe search parameter tests whether the value in a resource is subsumed by the specified value (is-a, or hierarchical relationships).
aboveAboveThe search parameter tests whether the value in a resource subsumes the specified value (is-a, or hierarchical relationships).
typeTypeThe search parameter only applies to the Resource Type specified as a modifier (e.g. the modifier is not actually :type, but :Patient etc.).
identifierIdentifierThe search parameter applies to the identifier on the resource, not the reference.
ofTypeOf TypeThe 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.

Explanation of the columns that may appear on this page:

LvlA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
