Hiding all rows with inexact matches

Hi, and welcome to ExcelForums. This place has taught me a ton, and I'm just now myself starting to feeling comfortable and confident enough in offering help and advice back to other's.

How's something like this?

I did a compare of the two fields and returned a True or False. True is a Match found. That formula is as follows

=ISNUMBER(SEARCH(B2,A2))

Then I searched that True/False cell range hiding any 'True' Values.

Sub HideMatch()
    Dim rows_rng As Range, rows2hide As Range
    Dim rCell As Range
    
    Set rows_rng = Range("C2:C5")
        
    For Each rCell In rows_rng
        If rCell.Value = "True" Then
            If rows2hide Is Nothing Then Set rows2hide = rCell Else Set rows2hide = Union(rCell, rows2hide)
        End If
    Next

    Application.ScreenUpdating = 0
    rows_rng.EntireRow.Hidden = 0
    If Not rows2hide Is Nothing Then rows2hide.EntireRow.Hidden = 1
    
    Application.ScreenUpdating = 1
End Sub
