Search function in Atlas not returning expected values

Testing Atlas with LOINC and SNOMED vocabularies loaded, some concepts don’t seem to load as expected.

If we use SEARCH function for ‘MCV’ in demo atlas: it returns 5 LOINC codes

when we replicate same search in local atlas it returns only 1, without the most frequently used code

Is there an additional expansion step needed to confirm full vocabulary load?

Many Thanks,
Holt Oliver
