Search box applying autofilter - need partial results

[sniper26]

Hi all,

I have the below code working but it only returns exact matches. Is there a way to return the partial matches? Any help would be greatly appreciated!

For example, if I search for "123", I would want it to return both row 1 and 3.

Col A
123-456
234-987
123-789

Sub SearchBox()
'PURPOSE: Filter Data on User-Determined Column & Text/Numerical value

Dim myButton As OptionButton
Dim SearchString As String
Dim ButtonName As String
Dim sht As Worksheet
Dim myField As Long

Dim mySearch As Variant

  Set sht = ActiveSheet


'Unfilter Data (if necessary)
  On Error Resume Next
    sht.ShowAllData

  Set DataRange = sht.Range("A3:E59") 'Cell Range

    SearchString = "=" & mySearch
  Else
    SearchString = "=*" & mySearch & "*"
  End If

    If myButton.Value = 1 Then
      ButtonName = myButton.Text
