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.).

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
