Query using multiple values from one text box

Hi,

I have a form called Test. On this form, I have a textbox where I can
type query criteria. I would like to be able to type multiple criteria
into this textbox and use this textbox to filter my query results.

For example, on my Test form textbox, I'd like to be able to type
("Alaska" OR "Alabama") and would like to then filter my query based
on what I type into this textbox.

Currently, when I type one thing into the textbox "Alaska," the query
properly filters to all results that equal "Alaska." However, when I
type another piece of critiera "AND Alabama" or "OR Alabama", the
query returns no results.

How can I accomplish this?

Thanks
