The
hierarchies in SNOMED CT support searches to be constrained by type, e.g. searches for Concepts which are contained in one of the top-level hierarchies such as
| Concept |
|---|
| ShowParts | term |
|---|
| t | | clinical finding | |
|---|
|
, | Concept |
|---|
| ShowParts | term |
|---|
| t | | body structure | |
|---|
|
and
| Concept |
|---|
| ShowParts | term |
|---|
| t | | procedure | |
|---|
|
(see
4.4.2. Constrain Searches by Supertype Ancestors).

This type of search limits the number of search candidates significantly, as it excludes all Concepts of types other than those specified by the chosen subtype hierarchy. More granular Concepts than the top-level Concepts can be used as the basis for this type of search. For instance, searching for subtypes of
| Concept |
|---|
| ShowParts | term |
|---|
| t | | Cardiovascular finding | |
|---|
|
will further concentrate the type and number of candidate results.

It is a benefit that SNOMED CT supports development of Language Reference Sets, as this supports searches by Descriptions that are limited to a specific language or dialect (see 4.4.4. Constrain Searches by Language or Dialect). A Language
identifies the
which are considered to be preferred designation for and acceptable as alternatives for SNOMED CT Concepts in the context of a given language and, optionally,
