Today Google announced a new feature of STARS to give a better personalized search. This will help us to mark some results as favorite and we can get this on the top of the list whenever we search for the same thing again. It will be fantastic as lot of times I want to go back to the same old link that I goggled, but till now there was no way except bookmarks! Google will start rolling this out in coming days to all its users.
With stars, you can simply click the star marker on any search result or map and the next time you perform a search, that item will appear in a special list right at the top of your results when relevant.
