according to the post here,google started censoring search results for torrent and rapidshare links.
What Google has done, is make a list of piracy-related keywords that have been removed from its auto-complete list. For instance, anything with the word torrent(including utorrent,a perfectly legal software) added to it will not be suggested by the search engine. What is a little weird here, though, is the fact that Google hasn’t banned words like Pirate Bay or ISOHUNT, which are popular torrent sites.
So,what are you now going to do?use duckduckgo.it could be added to firefox search bar easily too.
