Multi-Concept Search

You can find mentions of a clinical terms by searching for equivalent representations within an ontology. This is possible because when the NLP API extracts a medical term, its also maps the term and its synonyms to concepts that represent that clinical idea in the ontologies used during document processing. For example, when the SNOMED CT ontology is used, the term diabetes is mapped to the SNOMED concept 73211009 | Diabetes mellitus (disorder). The association between diabetes and its unique identifier in SNOMED is permanent and unchangeable (i.e. will not change between revisions of the SNOMED ontology).

This section provides example of how to search for clinical terms by concept ID. This query pattern is very useful as it allows you to search for a set of related or arbitrary concepts of interest.
