Search a List Using Another List in Excel 2010

Question

VLOOKUP is maxing out and refusing to complete my search request.  I am querying a list of 199,000 rows with another list of 48 rows.  Excel says it is too hard.  Is there another way to do this?  (The answer posted on this site by an
earlier responder to a similar question was not helpful.  I do not want to use FIND to search name-by-name through the bigger list).

Firstly, would you please let us know what's your formula and source data looks like?If the VLOOKUP function indeed cant complete your search request,the VBA dictionary or sql  should be a good option for you.
Using VBA dictionary way to lookup value:
Sub Test()
Dim ds
Dim i&, irow1&, irow2&, j%, arr, arr1, arr2
Dim s
Application.ScreenUpdating = False
Set ds = CreateObject("scripting.dictionary")
irow1 = [A1048576].End(xlUp).Row
arr = Range("A1:A" & irow1)
irow2 = Sheets(1).[A1048576].End(xlUp).Row
arr1 = Sheets(1).Range("A1:B" & irow2)
arr2 = Sheets(1).Range("A1:B" & irow2)
On Error Resume Next
For i = 1 To irow2
ds.Add arr1(i, 1), i
Next
Err.Clear
On Error GoTo 0
For i = 1 To irow1
If arr(i, 1) <> "" Then
s = ""
s = ds(arr(i, 1))
If s <> "" Then
arr2(i, 1) = arr1(s, 2)
End If
If s = "" Then
arr2(i, 1) = ""
End If
End If
Next
[B1].Resize(irow1, 1) = arr2
Application.ScreenUpdating = True
End Sub
If you are not  familiar with VBA code or you just wanna another workaround,please fell free to let us know.
