Not A Case Sensitive Search?

Below is my sql search code in my asp page. But my search seems to be case sensitive. How can i modify it to make it not case sensitive?

<%
sqlString = "SELECT product_image, product_name, product_description, product_price " &_
"FROM Products " &_
"WHERE product_status = 1 " &_
"AND ( product_name LIKE '%" & searchFor & "%' " &_
"OR product_description LIKE '%" & searchFor & "%') " &_
"ORDER BY product_name "

SET RS = Conn.Execute( sqlString )
IF NOT RS.EOF AND searchFor <> "" THEN
%>
