Success! Found this on the web today and was able to leverage off it to find the code I needed!

Here's the SQL statement that worked, as entered into VBE:
sql_q = "SELECT DISTINCT * " & _
"FROM Vendor, qryPartSearch " & _
"WHERE (qryPartSearch.PrimVendor = [Vendor]![id]) OR (qryPartSearch.AltVendor Like '*' & [Vendor]![id] & '*' ) " & _
"ORDER BY id;"
Edit: By the way, is it possible to make the ORDER BY statement such that it puts the PrimVendor listing first, and the rest in numerical order afterwards?
