"Search Within A Search" article in ei magazine

I have an article in print in this months ei magazine - "Search within a search" - sadly the online version is for subscribers only. I hasten to add I didn't write my own blurb, which makes the whole thing sound like an exciting adventure with the BBC's only producer....

"It was what the brains at the BBC's new media and technology department least expected when they started a routine statistical measure. While measuring search usage, they discovered a way to decipher search queries from a two-million-page website to help provide better, more relevant answers. Martin Belam, departmental development producer, explains the process."
