Multi-system text filter
POST /ValueSet/$expand with an ad-hoc composed ValueSet spanning multiple code systems Expands an ad-hoc ValueSet that combines two or three code systems (SNOMED CT, LOINC, RxNorm) with a free-text filter. Pool covers four system combinations (all3, sct+loinc, sct+rxnorm, loinc+rxnorm) with counts of 10, 200, and 400. Small counts (10) test short-circuiting when the first system alone satisfies the request; larger counts force the server to query and merge results across multiple systems.
