I've installed tha faceted search xcelerator, but it doesn't work...The installation consist in copying some files into the taskspace deployment folder, and when I perform the copy, something extrange happens. Only one of the files that must be copied already exists in the folder with the exactly same name. If I replace it, the taskspace doesn't work any more (http 404 error), and if I don't do it, the taskspace works, but when I access to the search page absolutely nothing is displayed (I see the whole page in blank)....What am I doing wrong?
