GOOGLE CUSTOM SEARCH API - (searches related to function)
===

I need your help. I am looking to create a custom search engine.

I am currently looking at using the Google Custom search API. I tried looking into this but I couldn't find anything concrete. 

Is there any way to setup related search words on a Google Custom search website? Is there any API that can generate **"searches related to"**? 

Your help is much appreciated,
thanks,
Mike
