Good Idea Rated 4 out of 5 stars

Good idea, the only issue is that by default the HTTP URL is used instead of the HTTPS one. You can change this by editing the file privatelee.xml in your profile/searchplugins folder and just replace all occurrences of http://privatelee.qrobe.it by https://privatelee.qrobe.it. HTTPS is supported by the site and this way your communication with the search engine is now secure.
