This Code system is used in the following value sets:

4.2.11.search-param-type.1 Content

4.2.11.search-param-type.2 SearchParamType

Data types allowed to be used for search parameters.

This code system http://hl7.org/fhir/search-param-type defines the following codes:

CodeDisplayDefinition
number NumberSearch parameter SHALL be a number (a whole number, or a decimal).
date Date/DateTimeSearch parameter is on a date/time. The date format is the standard XML format, though other formats may be supported.

token TokenSearch parameter on a coded element or identifier. May be used to search through the text, displayname, code and code/codesystem (for codes) and label, system and key (for identifier). Its value is either a string or a pair of namespace and value, separated by a "|", depending on the modifier used.

uri URIA search parameter that searches on a URI (RFC 3986).

Explanation of the columns that may appear on this page:

LevelA 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
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)
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
