Chaining Operation in Gallery fails

[MBlack]

I am trying to chain two formulas together in a Gallery. Each of the filters works individually, but I can't seem to get them to work together. Like a lot of others, I have tried the ;; as well as Collect, but I still must be doing something wrong. Here are the formulas I'm trying to combine into one operation (not concurrent though):

Filter(
    Users, 
    IsMatch(
        'Full Name',
        "#",
        Contains
    ) <> true
)

and

SortByColumns(
	Search([@Users], 
	TextSearchBox1.Text, "fullname"), 
	"fullname", 
	If(SortDescending1, Descending, Ascending))

Can someone please point me to how to do this? I must not be writing the Solutions I have found correctly.

SortByColumns(
    Filter( Users, TextSearchBox1.Text in 'Full Name' && !("#" in 'Full Name') ),
    "fullname", If(SortDescending1, Descending, Ascending)
)
