How Combo Box Can Drill Down Results As I Type A Name

How can i do the following? In a combo box, how can i type in say PEPPER and see every formulaName that contains Pepper in their description. I would get back Red Pepper, Orange Pepper, Black Pepper, Pepper, to choose from. Notice that Pepper can be anywhere inside the name.

I would like the choices change as i type. In other words, if i type BL, i would start to see choices like Black Pepper, Blue Pepper, Roger Blueboy, Green Bloak or any formulaname containing BL.

I presently have the following combo box. if i start typing BL and hit the down arrow, i will see formulas starting with BL. unfortunately, furtherdown, i also see all the other thousands of formulas in the base; meaning I see things that start with C, D, E etc.

I was hoping that i would see every formula containing the letters that i type, As I Type. so if i went further and typed BLAC, the formulas that almost made the cut, disappear from view, leaving me with things having BLAC in name, anywhere in the formulaName. Is this possible? I kind of want to DRILL down. when i finish typing black, i would have all formulaNames that have the word Black somewhere.

here is the combo box after update code:
----------------------------------------------
Private Sub CboFormulaNameFilter_AfterUpdate()
If Me![CboFormulaNameFilter] = "<All>" Then
DoCmd.ShowAllRecords
Else
DoCmd.ApplyFilter , "[FormulaID] = Forms![frmFormulaMain]![cboFormulaNameFilter]"
End If
End Sub
------------------------------------------------

============================
Here is the row source sql code:

SELECT DISTINCT tblFormulaMain.FormulaName, tblFormulaMain.FormulaID, tblFormulaMain.Description, tblFormulaMain.FormulaStatus
FROM tblFormulaMain
GROUP BY tblFormulaMain.FormulaName, tblFormulaMain.FormulaID, tblFormulaMain.Description, tblFormulaMain.FormulaStatus
ORDER BY tblFormulaMain.FormulaName;
===============================

FormulaID is a text field.
