Description
This may be relevant to other coding terminologies but the use case I have is from SNOMED.
As a clinician developing SNOMED I want to use the SNOED hierachy to include/exclude long groups of codes in order to save me time including/excluding them one by one.
Take the search the hepatitis . It returns 1398 results on OpenCodelists and they are helpfully divided into the SNOMED hierarchies disorder, disposition, finding, medicinal product etc etc. I know immediately that I don't want to include medicinal products but the current model means I have to go through the children of medicinal product to exclude them one by one. It would be great If i just excluded medicinal product.

Research direction
Start with the hepatitis search in OpenCodelists and inspect how SNOMED hierarchy groups such as medicinal product are presented and selected. Define the selection behavior and verify that excluding a hierarchy excludes its descendants without requiring one-by-one selection.
