Specific property contains

Any property contains

Get all jcr:content nodes that

have a specific resourceType
have any property that contains a specific (text-) value
have a "grandchild" node, which has a specific resourceType
have a "grandchild" node, which has a property called "date" greater than "2012-06-01" and less than "2016-07-01"
and order the result by the date property in descending order.
