This is not new, but many of the folks out there are unaware of it. A search syntax at Google works as follows;
Search on ~*marketing will bold some the preceding words to marketing.
Search on ~*marketing*~ will bold some of the words in front of and behind the term marketing.
How is/was this useful? Well it was used often during the Latent Semantic Analysis (LSA) theory craze. :)
