Hi there.
Today I've tried the plugin and I am 100% sure that I will use it, but I have a problem with the encoding. My blog is Bulgarian language based, which means that there are many cyrillic searches. The problem is that the plugin don't properly display the characters and I get mostly ???? - ??????? or something like this.
Look at the screenshot.
