How this thing is works is like a mystery when I first put them on my blogs about half a year ago. I noticed that people had used it, but less than 1% of them had clicked on it as it works the same way as the most popular search engine. People were expecting things relating to my blogs, but they saw things from all over the web instead.
Just a while ago, I went to the search settings and saw this option highlighted in red below:
It was on "The entire web" option... no wonder. I entered the list of site people might be searching for below and it works! Reason why I didn't notice this earlier was that I never used it myself! :P
PS. This post wasn't planned, so this is my actual final post for 2008. The previous was the Autumn 2008 review on my main blog.
