Interesting Software: Search Visualizer
I won't try to explain this but will just suggest that you give it a try. It's Search Visualizer, a web-based system that processes search results from Google and other search engines and displays them in visual form. Here's an idea of how the results look, based on a sample search for data about the 787 Dreamliner's battery problems.
I've tried a variety of "search front-ends" over the years and so far have always ended up going back to plain old Google. I don't know whether Search Visualizer would meet the long-term usefulness test, but its approach is interesting. The company lays out scenarios in which it thinks such visualization would pay off. Over to you to see whether in your search circumstances it makes sense.
