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.

Let's see the allowed symbols...

Operator	Symbol
Equals to	=
Not equals to	!=
Greater than	>
Greater than or equals to	>=
Less than	<
Less than or equals to	<=

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.
