The synonym search in Google is represented by using the tilde symbol (~). Just insert that before the title words such as ~prgrammer, etc.
You may also want to start out with Broadlook's Title Research tool. It's a good place to start and then you can refine your titles from there. It is a desktop application and is completely free. I have it installed and it can be helpful. Although, I don't see the download link on the website anymore so you may have to email or call to get the free copy.
