Search multiple strings in a excel workbook - arrays

Question

I am trying to design a macro to search for multiple strings in an excel.
I have the following code which searches for the word "techno" in an excel but, I need to include a variable into the code so that I can search for multiple words such "Techno", "electromagnetic", "waves", etc. at once. I am unable to create a loop for this condition.
Can anyone suggest a solution to this problem? The below code works fine but, only a tweak is required to include multiple strings in the search.
Sub SearchFolders()
Dim xFso As Object
Dim xFld As Object
Dim xStrSearch As String
Dim xStrPath As String
Dim xStrFile As String
Dim xOut As Worksheet
Dim xWb As Workbook
Dim xWk As Worksheet
Dim xRow As Long
Dim xFound As Range
Dim xStrAddress As String
Dim xFileDialog As FileDialog
Dim xUpdate As Boolean
Dim xCount As Long
myArray = Array("techno", "magnetic", "laser", "trent")
On Error GoTo ErrHandler
Set xFileDialog = Application.FileDialog(msoFileDialogFolderPicker)
xFileDialog.AllowMultiSelect = False
xFileDialog.Title = "Select a forlder"
If xFileDialog.Show = -1 Then
xStrPath = xFileDialog.SelectedItems(1)
End If
If xStrPath = "" Then Exit Sub
xUpdate = Application.ScreenUpdating
Application.ScreenUpdating = False
Set xOut = Worksheets.Add
For myCounter = 0 To UBound(myArray)
MsgBox myCounter & " is the Count No."
xStrSearch = myArray(myCounter)
MsgBox xStrSearch & " is the Value fr String search"
xRow = 1
With xOut
.Cells(xRow, 1) = "Workbook"
.Cells(xRow, 2) = "Worksheet"
.Cells(xRow, 3) = "Cell"
.Cells(xRow, 4) = "Text in Cell"
Set xFso = CreateObject("Scripting.FileSystemObject")
Set xFld = xFso.GetFolder(xStrPath)
xStrFile = Dir(xStrPath & "*.xls*")
Do While xStrFile <> ""
Set xWb = Workbooks.Open(Filename:=xStrPath & "\" & xStrFile, UpdateLinks:=0, ReadOnly:=True, AddToMRU:=False)
For Each xWk In xWb.Worksheets
Set xFound = xWk.UsedRange.Find(xStrSearch)
MsgBox xFound & " is the strings found"
If Not xFound Is Nothing Then
xStrAddress = xFound.Address
End If
Do
If xFound Is Nothing Then
Exit Do
Else
xCount = xCount + 1
MsgBox xCount & " is the count of strings"
xRow = xRow + 1
.Cells(xRow, 1) = xWb.Name
.Cells(xRow, 2) = xWk.Name
.Cells(xRow, 3) = xFound.Address
.Cells(xRow, 4) = xFound.Value
End If
Set xFound = xWk.Cells.FindNext(After:=xFound)
MsgBox xFound & " next string"
MsgBox xStrAddress & " is the address "
MsgBox xFound.Address & " is the address found"
Loop While xStrAddress <> xFound.Address 'To check how xStrAddress is populated or do we need to declare it as a help from excel pointed out
myCounter = myCounter + 1
Next
xWb.Close (False)
xStrFile = Dir
Loop
.Columns("A:D").EntireColumn.AutoFit
End With
Next myCounter
MsgBox xCount & "cells have been found", ,
ExitHandler:
Set xOut = Nothing
Set xWk = Nothing
Set xWb = Nothing
Set xFld = Nothing
Set xFso = Nothing
Application.ScreenUpdating = xUpdate
Exit Sub
ErrHandler:
MsgBox Err.Description, vbExclamation
Resume ExitHandler
End Sub

If the strings you are searching will always be the same, hard code them into an array and Loop through the array elements to search each string, like so:
Dim myArray as Variant
Dim myCounter as Long
myArray = Array("techno", "electromagnetic", ...etc.)
For myCounter = 0 To UBound(myArray)
... 'your code here
xStrSearch = myArray(myCounter)
... 'the rest if your code here
Next myCounter
