How are the tables linked to Access? Sometimes Access presents you with
a list of indexes and asks you to pick the unique identifier, so if you
do not tell it, then it assumes there is none.

Access is probably building its own index here and, although off topic,
this may well be the best way to set up your enquiry form. Is there any
difference in the filtering speeds on different columns?
