Filter each list within a column for lines that contain strings

Hello pelowski 

you can surround your custom function like this

let
	Source = #table 
	(
		{"Facility"},
		{ {"This is a test"}, {"this is fantastic"}, {"Test123"}, {"13:00 am"} } 
	),
	Facility = List.Select
	(
		Source[Facility], //your custom function goes here
	(
		listitem
	)=>
	List.AnyTrue
	(
		List.Transform
		(
			{"test","1"}, //words to be searched go here
			(
				transfrom
			)=>
			Text.Contains
			(
				listitem,
				transfrom,
				Comparer.OrdinalIgnoreCase
			)
		)
)
)
 in 
	Facility
