Look for multiple strings in a cell

Hi,

I would like to check if any of 'n' strings in a cell and return "found" if any of the 'n' strings is found in the cell.

Example:

A1 contains - "MAYURI FOODS AND VIDEO REDMOND WA"

A2 should display "found" if A1 contains one of the values "FOOD, APNA, UDUPI"

I tried =IF(COUNTIF(B167,{"*MAYURI*","*APNA*","*UDUPI*"}),"found") . But it did not work.

Can any one give me a solution to my requirement?

Thanks in advance.
