All codes from system http://hl7.org/fhir/search-modifier-code
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, or Identifier.type.text. |
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. |
ofType | 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. |

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 |
