Query for pair-wise attributes

[Yu]

Hi, 

I'm working on a project using CQEngine, and there's a use case that I'm not sure how I can solve using the attributes class. It will be great if I can get any input from you. 

Say we have a data schema like the following:

Entity{

   String name;

   List<Tag> tagList; 

}

Tag {

   String key;

   String value;

}

Is there any good way we can do if we want to support the query for both the tag key and the tag value? Something like "tag.key contains xxx and tag.value not equal yyy".

Thanks in advance!

Yu

Yes that is possible. For an example see: https://stackoverflow.com/questions/37766895/can-cqengine-query-an-object-inside-another-object
