Yes, wildcards can be used in Access. How to do so depends on where they
are searching. You say "doing a search" and "in the entry field". Neither
of these are Access terms. Where are they searching? Are they building a
query? Are they filtering a form? Waht "entry field".
If you need more specifics, you will have to give us specifics. We can't
see your screen. We have no idea how your file is structured. If someone
posted that exact question to you in email, would you have any idea how to
answer it?
