If an object contains inherent dictionaries (that usually contain custom keys) in its properties, like:
{ id: '1234' customInfo: { customProperty1: value1, customProperty2: value2} }

How is it expected to perform filtering and sorting on collections of such objects?

For example:
/collectionName?orderBy=customInfo.customProperty1

Or
/collectionName?filter=customInfo.customProperty1 eq value1

Is this acceptable?

Thank you!
