The serendipity suggestions take longer to generate than before, as the the code now considers keyword phrases returned by answers.com, instead of just single keywords. As an example, here's what appears if I try searching for the film "Faraway, So Close" on our OPAC:
Obviously the suggestion of searching for "Close Faraday" is of little use. However, most of the serendipity suggestions are relevant to the film, and at least two of them will lead me straight through to the catalogue page for "Der Himmel Ã¼ber Berlin" (the prequel to "Faraway, So Close").
One rather cool outcome of this is that our OPAC can now sometimes answer questions! Sadly the results don't always lead to relevant items, but at least our OPAC knows the answer to the Ultimate Question!
