This Code system is used in the following value sets:

Data types allowed to be used for search parameters.

This code system http://hl7.org/fhir/search-param-type defines the following codes:
Code Display Definition
number Number Search parameter SHALL be a number (a whole number, or a decimal).
date Date/DateTime Search parameter is on a date/time. The date format is the standard XML format, though other formats may be supported.
string String Search parameter is a simple string, like a name part. Search is case-insensitive and accent-insensitive. May match just the start of a string. String parameters may contain spaces.
token Token Search parameter on a coded element or identifier. May be used to search through the text, display, 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.
reference Reference A reference to another resource (Reference or canonical).
composite Composite A composite search parameter that combines a search on two values together.
quantity Quantity A search parameter that searches on a quantity.
uri URI A search parameter that searches on a URI (RFC 3986).
special Special Special logic applies to this parameter per the description of the search parameter.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. 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
