This website has technology to identify words with domain names. Expired domain name lists are released daily with 50,000+ .com domains. This site identifies valid 1 to 5 dictionary words with in domain names and sorts them according to word count. This allows one to find a valuable domain name quickly and is the first time this has been offered for free. The site is, 1search.org and the lists can be found at 1search.org/category/expired-and-dropped-lists/ . (I can't post a link).
I found these domains for free today in a few minutes.
