Sorting records based on a couple or many criteria items from a qu

I currently have a query set up consisting of several fields from several
tables. I'd like to solicit advise on the best way to set up search
criteria. I've looked into building a dialog box containing combo boxes
where the source of the combo boxes are individual queries. This is exactly
the type of mechanism I'm looking for, but according to the documentation
I've read I can't have more than two or three of the combo boxes on the
dialog box as it creates a complex query. I have about eleven different
fields I'd like to have the option to sort on - maybe sorting the records on
many of them or just a few. Any advice on the best way of going about this
is appreciated.
