    Query search wont display null fields

    Hi, i have a query to search a form input value for a specific username. i am using the Like * function to select all if no username has been entered or if one is entered then it passes that into the sql query string instead. the problem with this is that the LIKE function doesnt return empty fields, only the fields with data in them. is there a way around this?? so it displays empty username records aswell as ones with the same username. code is below i am using, it must be able to fit in the null check and insert into the sql string. thanks

    Private Sub bob_Click()

    On Error GoTo Err_bob_Click

    Dim db As DAO.Database
    Dim qdf As DAO.QueryDef
    Dim strsql As String
    Dim strUserSearch As String

    Set db = CurrentDb


    Set qdf = db.QueryDefs("fullSearch")

    If IsNull(Me.userSearch.value) Then
    strUserSearch = " Like '*' "
    Else
    strUserSearch = "='" & Me.userSearch.value & "' "
    End If

    strsql = "SELECT dbo_HistoricalReport.*" & _
    "FROM dbo_HistoricalReport " & _
    "WHERE dbo_HistoricalReport.UserName" & strUserSearch & _
    ";"

    MsgBox strsql
    qdf.SQL = strsql

    DoCmd.OpenQuery "fullSearch"

    Set qdf = Nothing
    Set db = Nothing


    Exit_bob_Click:
    Exit Sub

    Err_bob_Click:
    MsgBox Err.Description
    Resume Exit_bob_Click

    End Sub
