How to filter multiple columns with many keywords?

Hi all,

I have a long list (360k) rows of information with 12 columns. I want to search three of these columns for certain keywords I have. The three columns are descriptions so they are not exact matches to the keywords.

I have the list of keywords (1100 of them) in a separate tab. How would I go about using these keywords to find any of the entries which contain these keywords in the 3 columns? I have tried to use advanced filtering but no luck.

Example:
I have columns A B and C. They contain descriptions I want to search through. I have a list of 1100 keywords & want to search columns A, B and C for them. If either column A, B or C contain the any of the keywords I want the row to show up. If it does not, I want it to be filtered out & hidden. Example in attached photo.

Sub test()
Dim lr As Long, x As Long, at As Integer, qt As Integer, arr As Variant
lr = Range("A" & Rows.Count).End(xlUp).Row
arr = Range("H1").CurrentRegion     'Column with keywords
For x = lr To 3 Step -1
    For i = 2 To UBound(arr)
        at = InStr(1, Range("A" & x) & " " & Range("B" & x) & " " & Range("C" & x), arr(i, 1) & " ", vbTextCompare)
        If at > 0 Then qt = qt + 1
    Next
    If qt = 0 Then Range("A" & x).EntireRow.Hidden = True
    qt = 0
Next
End Sub


Sub test2()
ActiveSheet.Rows.Hidden = False
End Sub

Kind regards
