Search for Parent value of Casading Select list Custom Field

Edgar Oregel_1g2cuw

I'm trying to create a JQL query to retrieve all tickets that have value VAL as the parent value of a cascading select list custom field. 

CustomField_0000 = "Value1" - "Value2"

In the above, I would like to query all tickets that have CustomerField_0000 = "Value1" - <any_second_value>

The cascadeOption() allows for JQL querying on Parent and/or Child values of cascading select list custom fields.
