Japan’s search engine “goo” has been creating variety of unique search engines such as blog search, map search, train schedule search, and Wikipedia article search. On Sept. 12, they open the test version of “5W1H Search“. With “5W1H”, after you enter search phrase, you select which results you’d like to see from 5W1H.

I entered “Def Leppard” in the search box – ’cause I love them 🙂 Top 10 results for “What?” included pages about Def Leppard from Wikipedia (Japanese page), Amazon, Universal Music, Hatena Diary, YouTube (English page) and some personal websites. Tope 10 results for “Who?” were very similar to that of “What?”, but the description was more about the band’s history. I didn’t see Def Leppard’s official website anywhere. It looked that it was designed to pick pages in Japanese.

The pages in the results for “When?” all had some dates (concert date, CD release date, etc.), and the pages in “Where?” results had dates and places such as concert and auction. The pages in “Why?” results all had words such as “because” and “that’s why”, and majority of the top 10 results for “How” were auction pages.

I know that it’s just a test version and just started, but I was a bit disappointed to see not much differences between some of the result pages. I’m sure they’ll make improvements to the search results in future. Otherwise, I don’t see the need for 6 different result pages.
