Google has announced that they have added a number of new features to Search Options, their search results filtering tool included in the search results page. The tool already provided a number of options for filtering results based on the when the pages were created and now can filter results from the past hour and from a specified date range. Results can now also be filtered to include more or fewer shopping sites. Users who are signed into a Google Account and Web History enabled can have results filtered to include or exclude pages they have already visited. The Search Options tool was released in May.
