@reptar if the role(s) allow for it, you can use the deployment id to search for the script id:

var scriptSearch = search.create({
	type: search.Type.SCRIPT_DEPLOYMENT,

	columns: search.createColumn({
		name: 'scriptid',
		join: 'script'
	})
})

scriptSearch.filters = search.createFilter({
	name: 'scriptid',
	operator: <http://search.Operator.IS|search.Operator.IS>,
	values: [deployment]
})
