SYMPTOMS

If a query over multiple catalogs exceeds the time limit for execution (the MaxQueryExecution Time registry parameter), Indexing Service does not report that the query timed out before it finished. Because of this, the client program cannot detect that the results returned by the query are incomplete.

MORE INFORMATION

For additional information about how to install Windows 2000 and Windows 2000 hotfixes at the same time, click the article number below to view the article in the Microsoft Knowledge Base:

After you install this hotfix, the "Rowset Query Status" property now returns the STAT_TIME_LIMIT_EXCEEDED (256) flag when the query has timed out.

The following Microsoft Visual Basic sample illustrates how to handle the time limit condition by using ADO with the OLE DB Provider for Index Server (MSIDXS):

    Dim RS As New ADODB.Recordset
    
    Const adOpenForwardOnly = 0
    Connect = "provider=msidxs"
 
    CommandText = "select filename,path,Size,Write  from (table server.Catalog1..scope() union all table server.Catalog2..scope())  where  contains('microsoft') or contains('copyright')"
   
    RS.Open CommandText, Connect, adOpenForwardOnly
         
    Do Until RS.EOF
        ... RS("Filename")
        ... 
        RS.MoveNext
    Loop
      
    Status = RS.Properties("Rowset Query Status")
    If (Status And 256) Then
      MsgBox ("Error: Time Limit Exceeded")
    End If
