Formal value Set definition (identifier http://hl7.org/fhir/vs/filter-operator): XML or JSON.
This value set defines its own codes:
The kind of operation to perform as part of a property based filter
This value set defines it's own terms in the system http://hl7.org/fhir/filter-operator
| Code | Display | Definition |
| = | The property value has the concept specified by the value. | |
| is-a | The property value has a concept that has an is-a relationship with the value. | |

| regex | The property value representation matches the regex specified in the value. |
These codes are used in the following places:
See the full registry of codes defined as part of FHIR.
The OID for the value set is 2.16.840.1.113883.4.642.2.177 (and the OID for the implicit code system is 2.16.840.1.113883.4.642.1.177) (OIDs are not used in FHIR, but may be used in v3, or OID based terminology systems).
Explanation of the columns that may appear on this page:
| Id | The internal identifier for the concept (when the value set defines its own codes) |
| Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies |
| 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) |
| Display | The display (used in the display element of a Coding) |
| Definition | An explanation of the meaning of the concept |
| Comments | Additional notes about how to use the code |
