Find a file in folder using different keywords VBA - vba

Question

I am a new to VBA. My issue is that I have a file that will be updated it into a specific folder by different users. Now everytime a user updates the file, the name of the file might not be the samefolder. However, I can narrow it down using specific keywords. I have been able to search for a file using a keyword but not multiple keywords. Please can you point me in the right direction on how I can use multiple keywords to find a file in a folder? Is it possible to write code that will work like the below?
Sub Start_countries()
Dim keyword, pathname, filename As String
pathname = "C:\XYZ\"
keyword = "lol" Or "rofl" Or "lmfao" Or "rotfl"
filename = Dir(pathname & "*.xls*")
Do While filename <> "*.xls*"
If LCase(filename) Like "*" & keyword & "*" Then
Set wb = Workbooks.Open(pathname & filename)
Find_count_sum_in_file filename
wb.Close SaveChanges:=True
Else
msgbox = "No file Found"
End If
Loop
End Sub

Try the following (adapted following your comment):
Private Const MAX_KWD = 5 ' use a constant to make sure everyone uses the same value
Sub Start_countries()
Dim keyword(1 To MAX_KWD), pathname As String
'Keywords for first file search
keyword(1) = "lol"
keyword(2) = "rofl"
keyword(3) = "lmfao"
keyword(4) = "rotfl"
pathname = "C:\XYZ1\"
search_for_files keyword(), pathname
'Keywords for second file search
keyword(1) = "omg"
keyword(2) = "fyi"
keyword(3) = "ok"
keyword(4) = "brb"
pathname = "C:\XYZ2\"
search_for_files keyword(), pathname
End Sub
Sub search_for_files(keyword(), pathname)
Dim filename As String, s As String
Dim i As Integer
filename = Dir(pathname & "*.xls*")
Do While InStr(filename, ".xls") <> 0
s = LCase(filename)
For i = 1 To MAX_KWD
If (InStr(s, keyword(i)) > 0) Then Exit For ' found!
Next i
If (i <= MAX_KWD) Then
Set WB = Workbooks.Open(pathname & filename)
Find_count_sum_in_file filename
WB.Close SaveChanges:=True
Else
MsgBox "No file Found"
End If
filename = Dir()
Loop
End Sub
Note that in Dim pathname, filename, s As String only s is declared as String; all others are declared as Variant (the As String does not apply to all variables declared on the line).
Note also that in your While filename <> "*.xls*" the test will be exact, i.e. it will look also for asterisks (*) in filename.
