MATCH/INDEX IF question

Hi all,

I'll keep it simple...

{=INDEX($A$1:$N$317,SMALL(IF($E$1:$E$317="BURSTING",ROW($E$1:$E$317)),ROW(1:1)),1)}

This brings me my first instance of a row containing "BURSTING" from column E.

How do I manipulate the formula to search for THREE things? For example, I need to retrieve the first instance of a row containing EITHER "BURSTING", "FOLDING" OR "INSERTING" from column E. And basically each line underneath will bring me the second instance, the third instance etc. by using the (2:2) (3:3) (4:4) and so on.

Hope you can help, thanks.

Lee.
