I mentioned a few context search engines yesterday. I found another one today. It is called Roll Your Own Search. Here is why you need to look at RollYo.
Rollyo puts the power of Yahoo! Search in your hands, by giving you the tools to create your own personal search engines – with no programming required. All you have to do is pick the sites you want to search, and we’ll create a custom search engine for you.
You specify a list of sites in your search roll and all your searches will be in the context of the sites your specified. It has a very simple, easy to use interface. I was amazed at some of the Highrollers who already use this service. Still puzzled why I did not find this earlier.
