For example, the following expression constraint will match all referencedComponentIds (i.e. SNOMED CT concept id) from the active
| Concept |
|---|
| t | 447562003 |ICD-10 complex map reference set| |
|---|
|
rows, which map to the ICD-10 code "J45.9"
(as a word prefix). When applied to the July 2021 international edition, this will match 59 concepts, including
,
| Concept |

| t | 707447008 |Exacerbation of severe persistent asthma (disorder)| |

and

Please note that by default, a word-prefix-any-order match is performed. Therefore the following expression constraint will match on rows that have a mapTarget of "J45.0", "J45.1",..., "J45.8", "J45.9" etc.

To ensure an exact string match is performed, a wildcard search (without an '*') is required. For example, the expression constraint below will only match rows that have a mapTarget of "J45.9".

Multiple field constraints can be applied within a reference set member filter. For example, the following expression constraint will return the referencedComponentId from the
| Concept |

| t | 447562003 |ICD-10 complex map reference set| |

|
rows, which have a mapGroup of "2", a mapPriority of "1" and a mapTarget of "J45.9".
