Through searching for older post, i found this formula below, however, as for the StrFnd part, it appears that there are too many words i entered inside the string and it split the rest to the next column and that makes the remain words exclude from the string. How can i alternate the formula so i can include a large amount of words in String for search. Thanks

Sub HiLightList()
Application.ScreenUpdating = False
Dim StrFnd As String, Rng As Range, i As Long
StrFnd = "dog,cat,pig,horse,man"
For i = 0 To UBound(Split(StrFnd, ","))
Set Rng = ActiveDocument.Range
With Rng.Find
.ClearFormatting
.Text = Split(StrFnd, ",")(i)
.Replacement.ClearFormatting
.Replacement.Highlight = True
.Replacement.Text = "^&"
.Forward = True
.Wrap = wdFindContinue
.Format = True
.MatchCase = False
.MatchWholeWord = True
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = True
.Execute Replace:=wdReplaceAll
End With
Next
Set Rng = Nothing
Application.ScreenUpdating = True
End Sub
