Thank you for your reply. Can you be more specific? I mean, how to set criteria in my program. For example, I want to set these criteria:  Geographic area = America  Time range = past 7 days  Category = Finance  Search key = VCB     And all data must be download from 12 a.m to 1 a.m on Sunday. Do I need any other statement to control this condition?  I would be kind of you to give me an example of code.  Thanks.
