'Koogle' is a pun on search engine Google and the traditional Jewish dish 'kugel'. The Hebrew language-site is split in to sections including news, a market place for people to sell second-hand goods and a business directory for everything from Kosher restaurants to bridalwear.
The site is designed to meet guidelines set down by orthodox rabbis, ensuring that no sexually explicit material is shown.
It will also filter out items that ultra-orthodox followers are not allowed to have in their homes, such as televisions.
The site will also not allow transactions on the Sabbath, when it is forbidden to work or undertake business.
According to Wikipedia, Koogle was also the brand name for marketed by Kraft Foods. It was first introduced in 1971 and discontinued later that decade.
