Encounter Period

date date A date within the period the Encounter lasted Encounter.period
here if i am using date search parameter which is of period type,
example structure of period:
“period”: {
“start”: “2015-01-15”,
then it will check with which date as period structure has two dates (start, end)
and how prefixes (eq,ge,le,gt,lt) will work with period types
