Find all keywords

Howdy,

in A2:A30 are several phrases that contain certain keywords. Keywords are F1:F8.
In B2:B30 I need a formula to every keyword phrases found in the A2:A30
Let's say the keywords are: house cat, table, sky
In A2 is the following sentence: The cat is in the house and play on the table.
In B2 formula should list: cat, house, table

In http://www.excelforum.com/showthread.php?t=1145804 it is a similar topic but list only one keyword .
Thank you in advance.
