Help finding text within a different cell

Hope some one can help me.

I have a list of nearly 1million lines of text in two columns.

Column A contains URLs
Column B contains Keywords which wear searched in google to return the URL.

I'm looking to search the text in column B and compare with the text in column A to try to find matching text.

For example;

C1: TRUE as the word "footasylum" in cell B1 is also found in cell A1
C2: TRUE as the word "footwear" in cell B2 is also found in cell A2
C3: TRUE as the word "nike" in cell B3 is also found in cell A3
C4: FAULSE as the neither the word "Fashion" nor "Sportswear" in cell B4 is found in cell A4.

I'm struggling to find the right formula. I've looked a LOOKUP, VLOOKUP, SEARCH, FIND, etc. but not sure what I'm doing.
One of the main issues is that in the URL column A the words are not separate to the rest of the text in the cell (i.e. they are surrounded by "http://www." & ".com" for example.

Any help would be really appreciated.

Genius! Thanks you, would never have got that in a million years. Thanks a bunch!

One last thing, as your obviously an expert!
Is there a way to make that formula return the value of the word it matched rather than just true or false?
