Find a string contains a substring

[rajtrader]

I have a column name Keyword1 in one table, which contains a single word in each row and a Title column in another table. I want to highlight the Title if it contains any word from the column Keyword1.

For that, I used CONTAINS() function, but it seems like it does not work with a list of words and the second parameter of the formula should be a text. 

How can we find if a string contains a substring from a list or column?
