I have a unique index on two properties in a class, and I want to open the instance by index key with one of the two properties is set to the empty string. Is this possible to perform?
I'm working on a requirement to loop through all encounter streamlets(SDA) to identify specific encounters based on an encounter extension property for a patient fetch request. However, this current process is time-consuming, and we need to create indexes for that property to quickly retrieve the expected results without going through all the encounter streamlets of a patient.
I would appreciate help on how to achieve this, as I couldn't find any documentation explaining how to create indexes on a SDA element.
