It looks to me like you are wanting a parameterized query, which will give the end users a 'search' capability based on the parameters you let them see.
I'm adding this link here to an identical posting by the OP in the SQL Server forum:

A general rant about DAP... Microsoft has ceased supporting them with A2007. A2007 will not even open them, so it looks like MS has decided they are a dead end technology. If you have invested heavily in them, I'm sorry to hear it! However, if you aren't too far in to be able to back up, I'd suggest taking a look at other technologies to make your database accessible via the Internet.
