Hi, I was wondering if I could get some clarification on the date parameter for Encounter. Dates are saved as periods. If i were to do date:ge:"1/1/2026 12:00:00AM", does this check with period.start or period.end? Or is it dynamic, where date:ge checks for period.start and date:le checks for period.end. Thank you!

The Encounter date search parameter maps to Encounter.period. When Medplum indexes this into the database, it stores only period.start (falling back to period.end if start is absent): This means all comparators (ge, le, gt, lt) operate against the single stored value, which is period.start. So: date=ge2026-01-01 checks if period.start >= 2026-01-01 date=le2026-01-01 checks if period.start <= 2026-01-01 It is not dynamic based on comparator direction. Both ge and le compare against period.start.
