Here are some other search engines which I have come across in recent days :
Sputtr - gather all your favourite serach engines on one page. Easy to customise and simple design.
Search Crystal - lets you search and compare multiple engines in one place.It is a search visualization tool that enables you to compare, remix and share results from the best web, image, video, blog, tagging, news engines, flickr images or RSS feeds.
You can embed searchCrystal as a widget on your site or blog to share personalized crystals, or use it to find out what is popular on Wikipedia or use the search analytics toolbox in your browser as a powerful competitive intelligence tool. A searchCrystal application is also available in Facebook.
Intelways - used to be called CrossEngine and is a one-stop online search service, a convenient and fast way to search for (almost) anything on the web, through its comprehensive set of search channels organized into different categories.
