Cohql - apply filter for value which is inside map or list

I am using cohql for querying cache. I have one cached object which has a Hashmap as a property. Now when get a cache using get(key) and get NamedCache object.

I want to apply filter based on some value of property which is present inside the map. I have used like this -

QueryHelper.createFilter(“Obj.map{‘propertyName’}= ‘xyz’ “)

QuertHelper.createFilter(“Obj.list[‘property’]”)

But not working.

Anybody has any idea ?

Or how we query for collection data ?

Working on complex data types in coherence cache is similar to as we work normally with Java APIs

For query map like object in cohql we can use For map - 

QueryHelper.createQuery(“Obj.get(‘key’) = ‘xyz’”)
