As we all remember at the end of 2010, Google provided tools “Instant Previews” which, as promised, soon had to appear in the Safari browser, which are equipped with all appliances at iOS.
This service is nothing but a preview of Web pages that could be significantly save time. The emergence of Instant Previews in Safari can enable the preview site to the search query.
Representatives of Google have so far refrained from any official statements and the feature currently doesn’t work. Apparently goes its full testing.
