I previously wrote about Wikipedia, the free online encyclopedia. It's a nice user-edited online encyclopedia with millions of topics, but the Wikipedia's site search does not offer a great user experience. A website called FactBug.org offers an alternate means of searching the Wikipedia. The main advantage is that FactBug will present you with more search results in a more readable fashion.
On the other hand, if you know exactly what you are looking for, Wikipedia does offer the option to "Go" directly to the topic you are interested in. For example, if I want to learn about Florida, I just type in "Florida" and hit "Go".
Of course, while FactBug simply lists out all Wikipedia links that meet your query criteria and Wikipedia is good at some things and not so good at others, you can always use Google to search the Wikipedia. After your query phrase, just type in site:wikipedia.org. For example, here's what I would type into Google if I want to search for Florida results:
The advantage of Google is that they will likely show you the results that are most relevant.
