hasSubtasks()

Description:

Searches issues with / without subtasks, additionally you can further refine your query by using a number expression.

Note:

A 'number expression' is made of an optional operator representing by its mathematical symbol and a (prositive/negative) number.

By default, this function only includes issues with at least one subtask even if you use the '<' or '<=' operator.
   You must explicity add 'issues NOT IN hasSubtasks()' clause to your query, if you also want to search for issues without subtasks.

Examples:

• Find issues without subtasks:

issue NOT IN hasSubtasks()

• Find Stories that have three or more subtasks

type = Story AND issue IN hasSubtasks(">= 3")

• Find issues within the EMEA project having less than 2 subtasks or with no subtasks at all.

project = EMEA AND (issue IN hasSubtasks("< 2") OR issue NOT IN hasSubtasks())
