Collecta claims to provide results in real-time from the Web. Your search results will appear in a constantly-reloading stream — everything from Twitter updates to news and blog articles, and even Flickr photos.
However, Twitter usually deluges the results. The “Search Options” to the left of the results allows you to select the type of updates you want to see. Leaving the Twitter updates unchecked makes it easier to see the other real-time search results.
Like all Meta search engines, it is hard to create a search statement because you’re searching 140-character Tweets, full-text news, and Blog entries. I don’t use this as a starting point. However, it searches a wide variety of places, which makes it good for tracking breaking news.
