I’ve modified XooMLe slightly (Search, Spell and Cache) so that they use a local copy of the Google WSDL, rather than retrieving the remote one, because it speeds things up slightly (one less remote request).
Everything appears to be operating correctly on all operations still, so all’s well. I will also be releasing a downloadable version of XooMLe soon, so that you can host it on your own server and more thoroughly integrate it with your own search solutions.
XooMLe will be a free download when it becomes available (hopefully within a week). Sign up to the mailing list on the XooMLe Project Page to be the first to know when it’s available.
