Question:
Why does Orion Context Broker not return all the entities expected by a query with a pattern expression?

Description:
Some days ago when I made a query to Orion context broker with regular expressions, the response included all the entities that match that regular expression, now only retrieve the data of the older entities and if i want to access to the most recent entities, I need to make another request with a more specific regular expression.

The problem is that now I need to make two different querys with differents regular expression to retrieve the old and new entities when a week ago I only had to make one with the most generic regular expression.

Imagine that the structure of the id of my entities are:

dev:name_proyect:name_object:name_service

Some days ago I only need this generic expression to retrieve all the data:

dev:name_proyect:.*

Now I need two queryes to obtain the same result:

dev:name_proyect:.* -> the response only include old entities
dev:name_proyect:name_object:.* ->the response retrieve only the new data

So, the use of regular expression have changed in Orion CB? I need to do something else now to retrieve all the data with only one query with the most generic regular expression?

The instance of Orion that I am using is:
